  • How do I suppress this output?

    - by David
    I have a code chunk in an R Markdown file. ```{r} library(UsingR) ``` Using knitHTML to compile causes the following output, which never happened before I updated to the latest versions of R and RStudio: ## Loading required package: MASS ## Loading required package: HistData ## Loading required package: Hmisc ## Loading required package: grid ## Loading required package: lattice ## Loading required package: survival ## Loading required package: splines ## Loading required package: Formula ## ## Attaching package: 'Hmisc' ## ## The following objects are masked from 'package:base': ## ## format.pval, round.POSIXt, trunc.POSIXt, units ## ## Loading required package: aplpack ## Loading required package: tcltk ## Loading required package: quantreg ## Loading required package: SparseM ## ## Attaching package: 'SparseM' ## ## The following object is masked from 'package:base': ## ## backsolve ## ## ## Attaching package: 'quantreg' ## ## The following object is masked from 'package:Hmisc': ## ## latex ## ## The following object is masked from 'package:survival': ## ## untangle.specials ## ## ## Attaching package: 'UsingR' ## ## The following object is masked from 'package:survival': ## ## cancer How can I suppress this output?

  • Best Practice for Exporting an App's Data to XML via PHP/MySQL?

    - by Alex Cook
    I have an a business app and I want to give my users the ability to export their data at anytime. I'm aware that I can write an XML file semi-manually by doing something like this: http://www.kirupa.com/web/mysql_xml_php.htm But, I thought I'd ask if this is the best practice? Or is there some framework I can use to do this more easily/quickly? Maybe there isn't - it won't be too hard to do it the above way. Also, less importantly - XML is the best format to export to, right? Thanks in advance.

  • How do I remove specific numbers from a string?

    - by user1666900
    I have this string in PHP Hopelessly Incredible |SPG:M| 766 STEAM_0:1:20130600 " banned "A Blatantly Obvious Hacker 740 STEAM_0:1:55386073 " (minutes "0") (reason "Multi-Hack") The Format of the string is: Name1 Number(0-3 digits) Steam_0:x:xxxx offense (banned/kicked/mute etc) Name2 Number(0-3 digits) Steam_0:x:xxxx time reason My goal is to remove the values 766 and 740 because it is just garbage. Those values can have single, double, and triple digits. The next step would be to strip STEAM_0:1:20130600 and STEAM_0:1:55386073 out of the string and capture it in a new variable. The only constant is STEAM_0: the rest can change. I am still learning regex but I fear this is a bit complicated for me to do. Some guidance would be most appreciative.

  • how can I split up this string

    - by lacrosse1991
    I am currently trying to sanitize some log files so they are in an easier format to read, and have been trying to use the gnu cut command, which works fairly well, although I cannot really think of a good way to remove the [INFO] part of the string logs/logs/server_1283258036.log:2010-08-31 23:06:51 [INFO] <NateMar> where?! logs/logs/server_1281904775.log:2010-08-15 22:59:53 [INFO] <BoonTheMoon> §b<BoonTheMoon>§ohhhhhh I would ultimately want to get the strings down to something that resembles the following 2010-08-31 23:06:51 <NateMar> where?! 2010-08-15 22:59:53 <BoonTheMoon> ohhhhhh how should I go about doing this? Have thought about using awk, although Im having a difficult time getting a grip on how that would work, so not sure how to set up something to do that, any help would be greatly appreciated, thanks!

  • Tools for displaying text, powerpoint style, in linux

    - by Will Mc
    I have a problem where I need a way to display a repeating series of "images" on a computer monitor. Specifically, given a series of text files, I'd like a way to display the contents of said files on a screen in a way much like a powerpoint would. My current thoughts are to find some tool that will take in a text file of some format, and then output an image which contains the text from the file. Then I'd put it in a directory and have some Slideshow program continuously go between the images in that directory. It's a very hacky solution, obviously. So, does anyone know of tools that would do such a thing? Or is there a better way to do this? I've looked into the library libgd2, but it doesn't seem to support text-wrapping for images, which is something I'd need. Thanks!

  • How to create an image from canvas data?

    - by Jakub Hampl
    In my application I am trying to save an arbitrary part of a rendered HTML canvas to an image file. In my Javascript I call ctx.getImageData(x, y, w, h) and pass the resulting object to my macruby code (though if you know a solution in objc I am also very interested). There I'm trying to create a NSBitmapImageRep object so that I can then save to an image format the user desires. This is my code so far (the function gets a WebScriptObject as it's argument): def setimagedata(d) w = d.valueForKey("width").to_i h = d.valueForKey("height").to_i data = Pointer.new(:char, d.valueForKey("data").valueForKey("length").to_i) d.valueForKey("data").valueForKey("length").to_i.times do |i| data[i] = d.valueForKey("data").webScriptValueAtIndex(i).to_i end puts "data complete" # get's called @exported_image = NSBitmapImageRep.alloc.initWithBitmapDataPlanes(data, pixelsWide: w, pixelsHigh:h, bitsPerSample: 32, samplesPerPixel: 4, hasAlpha: true, isPlanar: false, colorSpaceName: NSCalibratedRGBColorSpace, bitmapFormat: NSAlphaNonpremultipliedBitmapFormat, bytesPerRow: 0, bitsPerPixel: 0) puts "done" # doesn't get called end The code doesn't seem to get through the initWithBitmapDataPlanes function but gives no error. My question is: what am I doing wrong? Is this approach reasonable (if not, what would be better?).

  • Interpreting Accept Headers as intended in IE and Webkit

    - by Jrgns
    I developed a web app that responds with data in the format as specified by the client in the HTTP Accept Headers. Everything worked fine while using Firefox, but when I wanted to check my CSS / HTML on Chrome and IE, both of them wanted to download the index page, as if it's an unknown content type. After some research I found this article, which states that IE sends out a lot of crud in it's HTTP Accept headers, amongst others a list of image/* content types right at the start. This caused my web app to try to send the index page as an image/jpeg. So how do I know when to ignore and when to use the Accept Headers?

  • GQL Query with __key__ in List of KEYs

    - by bossylobster
    In the GQL reference [1], it is encouraged to use the IN keyword with a list of values, and to construct a Key from hand the GQL query SELECT * FROM MyModel WHERE __key__ = KEY('MyModel', 'my_model_key') will succeed. However, using the code you would expect to work: SELECT * FROM MyModel WHERE __key__ IN (KEY('MyModel', 'my_model_key1'), KEY('MyModel', 'my_model_key2')) in the Datastore Viewer, there is a complaint of "Invalid GQL query string." What is the correct way to format such a query? [1] http://code.google.com/appengine/docs/python/datastore/gqlreference.html PS I know there are more efficient ways to do this in Python (without constructing a GQL query) and using the remote_api, but each call to the remote_api counts against quota. In an environment where quota is not (necessarily) free, quick and dirty queries are very helpful.

  • Help with dates in Android

    - by SamRowley
    Hi guys, Looking for a bit of help with taking a dat from a DatePicker Widget and storing it in an sqlite database within the app. I have the following code: java.util.Date utilDate = null; String y = Integer.toString(date.getDayOfMonth()) + "/" + (date.getMonth()+1) + "/" + Integer.toString(date.getYear()); SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyy"); utilDate = formatter.parse(y); java.sql.Date z = new java.sql.Date(utilDate.getDate()); x = z.toString(); Log.v("The date: ", x); } Where date is the DatePicker widget. If I output the utilDate variable (i.e. the Java version of date) using logCat it seems to work fine and gives me a format like: Tue Jan 04 00:00:00 GMT 2011 which I am expecting but using the code above to get the sql version of the date, it always gives me the date 1970-01-01. I'm pretty sure the solution is very simple but I just can't see it.

  • C++ - Print Out Objects From Set

    - by John Smith
    If I have a C++ set, declaration set personList; with iterator, set::const_iterator location; how can I print out the contents of the set? They are all person objects, and I have overridden the operator<< for Person. The line that errors is: cout << location and it's in a basic for loop. Netbeans gives the following error: proj.cpp:78: error: no match for ‘operator<<’ in ‘std::cout << location’ so it looks like it wants an override for the iterator's <<. Basically, I am taking objects that used to be stored in an array format, but are now in a set. What is the equivalent to cout << array[i] for sets?

  • How to set the ReturnUrl for the Login link in MVC 3 app?

    - by user762196
    using System; using Microsoft.Practices.Unity; namespace <MyNameSpace> { public class UrlFactory { public static UrlFactory Current { get { return HttpApplicationUnityContext.Current.Resolve<UrlFactory>(); } } public string GetLoginUrl() { return String.Format("{0}/login?ReturnUrl={1}", MyConfig.BaseHttpUrl, <GET_PAGE_URL>); } } The user can be on any page on the site and click the Login link. But the ReturnUrl must always point to the exact page where he clicked it. I must take the user back to the page he clicked the login link. In my code above, how do I get the page url in <GET_PAGE_URL>? Thanks

  • Processing XML file with Huge data

    - by Manish Dhanotiya
    Hi,be m I am working on an application which has below requiements - 1. Download a ZIP file from a server. 2. Uncompress the ZIP file, get the content (which is in XML format) from this file into a String. 3. Pass this content into another method for parsing and further processing. Now, my concerns here is the XML file may be of Huge size say like '100MB', and my JVM has memory of only 512 MB, so how can I get this content into Chunks and pass for Parsing and then insert the data into PL/SQL tables. Since there can be multiple requests running at the same time and considering 512MB of memory what will be the best possible to process this. How I can get the data into Chunks and pass it as Stream for XML parsing. I googled on this, but didnt find any implementation. :( Thanks,

    Hello, I am trying to find a way to calculate a duration in days between my, time zone (Central), and (Pacific; Mountain; Eastern). Just do not know where to start. My criteria would be as follows: Cell C5:C100 would be the timestamps in this format:3/18/2010 23:45 but for different dates and times. Cell D5:D100 would be the corresponding timezone in text form: Pacific; Mountain; Eastern; Central. Cell F5 would be where the duration in days would need to be.

  • jQuery ajax() and cakePHP urls

    - by Pickledegg
    I'm trying to call the 'tariff' action of my 'countries' controller using jQuery ajax() and pass it a country name in the following format: /countries/tariff/countryname however, with the following code ( set to GET ), it is calling this with the get '?' added: /countries/tariff/?countryname $(document).ready(function(){ $('#CountriesIndexForm select').change(function(){ $.ajax({ type: "GET", url: "/countries/tariff/", data: escape($(this).val()), success: function(html){ $(this).parent().next('div').html(html); } }); }); }); I understand its because the type: is set to GET, but is there a fix for this?

  • Android sending SOAP object over Https via ksoap2 2.5.8

    - by Jack-V
    My first time posting a question here so please do not mind my mistakes here. I'm currently making an android application fetching and sending information from a .asmx web service. Everything goes well with the ksoap2 library and am using HttpTransportSE to call the web service. So now what I'm trying to do is to use the HttpsTransportSE to call the web service over Https. I got java.security.cert.certpathvalidatorexception trustanchor for certpath not found exception. I have the server certificate in .pfx , .jks and .bks format. My questions is what do i do with it to make my HttpsTransportSE call to be success? I've read around with articles using custom SSLSocketFactory but am still not sure how to implement it in my application. Thanks in advance for any suggestion/advices

  • Is MS Access still the most efficient RAD tool for small-scale custom apps?

    - by FastAl
    Of the many other development tools I've used, nothing holds a candle to the 'Functionality to Development Effort' ratio of MS Access. The reason I am asking is that I have been out of the language selection process for a few years, working on a large .Net system, and am only anecdotally familiar with the latest development tools outside the .Net world. I'm well aware of the limitations of Access, but for a limited concurrency (usually only 1 user at a time), small business, custom app, has anybody found a comparable end-to-end solution or combination that comes close? It doesn't have to be free, open source, or even Windows based. It just has to allow the same speed of development and maintenance, and maybe even provide some additional amenities like seamless autointegration with a server-based DB Engine (like Access does with its own 'Jet' dbms), better web support, and a file format more compatible with source control. I don't want to miss out on anything. Please share your development experience with your suggestions. Thanks.

  • Rendering Views as String with Spring MVC and Apache Tiles

    - by lynxforest
    I am trying to reuse some of my tiles in a controller which is returning a json response to the client. I would like to return a json response similar to the following format: { 'success': <true or false>, 'response': <the contents of an apache tile> } In my controller I would like to perform logic similar to this pseudocode: boolean valid = validator.validate(modelObj) String response = "" if(valid){ response = successView.render() // im looking for a way to actually accomplish // this, where the successView is the apache tiles view. // I would also need to pass a model map to the view somehow. }else{ response = errorView.render() } writeJsonResponse(httpResponse, /* a Map whose json representation looks like the one I described above. */)

  • Is there a way to highlight specific words or numbers without inserting a span tag?

    - by Taylor
    I've got blocks of text with various specs in them and want to have jquery highlight whatever matches a specific pattern without inserting any extra html. The following is the kind of text that I've got to work with. Intel® Core™ i7 Processor 920 (2.66GHz, 8MB cache, 4.8GT/sec)/ Genuine Windows® 7 Home Premium 64bit- English/ 640 GB Serial ATA non Raid (7200 Rpm)/ 6GB 1333MHz (3x2GB) Tri Channel Memory/ Display Not Included/ 16X DVD+/- RW Optical Drive (DVD & CD read and write)/ 1.8GB NVIDIA® GeForce™ GTX260 graphics card/ Integrated HDA 7.1 Dolby Digital Audio What I'm hoping jquery can do is highlight some of the basic specs without inserting any extra html. Maybe working off a list of values matching the spec format using some wildcards where neededed? The css to select the correct tag is #list div div div+p or I could just give the p class but would rather not. Is this kind of thing possible?

  • Perl module for parsing natural language time duration specifications (similar to the "at" command)?

    - by Ryan Thompson
    I'm writing a perl script that takes a "duration" option, and I'd like to be able to specify this duration in a fairly flexible manner, as opposed to only taking a single unit (e.g. number of seconds). The UNIX at command implements this kind of behavior, by allowing specifications such as "now + 3 hours + 2 days". For my program, the "now" part is implied, so I just want to parse the stuff after the plus sign. (Note: the at command also parses exact date specifications, but I only want to parse durations.) Is there a perl module for parsing duration specifications like this? I don't need the exact syntax accepted by at, just any reasonable syntax for specifying time durations. Edit: Basically, I want something like DateTime::Format::Flexible for durations instead of dates.

  • Does anyone use AODL in a real application?

    - by HyperQuantum
    We are currently using the Excel interop API in .NET to generate simple spreadsheet documents from a template. So we load the template first, insert some rows, fill in some data (dates, text, and numbers), and make Excel visible so that the user can print or save the document we just generated. But I'd like to get rid of the Excel dependency, and switch to the ODF format as well. Googling suggests AODL (C# libs for generating ODF docs) as the most obvious solution. But their last release is 1.3.0.0 BETA, and seems to be 3 years old. So I'm not sure if it's a good idea to depend on a potentially dead project... In that case, I'd need to find another solution. Any ideas? Or maybe someone could assure me that AODL is still alive?

  • Making a web interface for neo4j

    - by user2898839
    I have a local neo4j database server and I want to build a web interface using javascript. Ideally I want to do all the querying and display the result client side for the website. I am mostly a Java programmer and unfortunately don't have much experience with Javascript. How can I do a cypher query from the website and return the result in a format which I can display easily in a table for example? I have seen examples of doing the querying server side with servlets or node.js but really would like to just have the neo4j server and the website client. I would be interesting in seeing a small working example if it is at all possible. Thanks for your time.
