  • plot only x and y axis (no box) in ggplot2

    - by Tyler Rinker
    The convention of some journals is to show only the x and y axis in a plot not a box around the entire plot area. How can I achieve this in ggplot2? I tried theme_minimal_cb_L from HERE but it seems to erase the entire box around the plot (does not leave the x and y axis) as seen here: Here's the code I'm using: dat <- structure(list(x = c(0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3), y1 = c(34, 30, 26, 23, 21, 19, 17, 16, 15, 13, 12, 12, 11), y2 = c(45, 39, 34, 31, 28, 25, 23, 21, 19, 17, 16, 15, 14)), .Names = c("x", "y1", "y2"), row.names = c(NA, -13L), class = "data.frame") library(reshape2); library(ggplot2) dat2 <- melt(dat, id='x') theme_minimal_cb_L <- function (base_size = 12, base_family = "", ...){ modifyList (theme_minimal (base_size = base_size, base_family = base_family), list (axis.line = element_line (colour = "black"))) } ggplot(data=dat2, aes(x=x, y=value, color=variable)) + geom_point(size=3) + geom_line(size=.5) + theme_minimal_cb_L()

  • PHP Image content type problem

    - by Mirko
    Hi everybody, I have a specific problem, and cant get over it. For my latest project I need a simple PHP script that display an image according to its ID sent through URL. Here's the code: header("Content-type: image/jpeg"); $img = $_GET["img"]; echo file_get_contents("http://www.somesite.hr/images/$img"); The problem is that the image doesn't show although the browser recognizes it (i can see it in the page title), instead I get the image URL printed out. It doesn't work neither on a server with remote access allowed nor with one without. Also, nothing is printed or echoed before the header. I wonder if it is a content type error, or something else. Thanks in advance.

  • Object to Network serialization - with an existing protocol

    - by cpf
    I'm writing a client for a server program written in C++. As is not unusual, all the networking protocol is in a format where packets can be easily memcopied into/out of a C++ structure (1 byte packet code, then different arrangements per packet type). I could do the same thing in C#, but is there an easier way, especially considering lots of the data is fixed-length char arrays that I want to play with as strings? Or should I just suck it up and convert types as needed? I've looked at using the ISerializable interface, but it doesnt look as low level as is required.

  • Most Efficient way to set Register to 1 or (-1)

    - by Bob
    I am taking an assembly course now, and the guy who checks our home assignments is a very pedantic old-school optimization freak. For example he deducts 10% if he sees: mov ax, 0 instead of: xor ax,ax even if it's only used once. I am not a complete beginner in assembly programing but I'm not an optimization expert, so I need your help in something (might be a very stupid question but I'll ask anyway): if I need to set a register value to 1 or (-1) is it better to use: mov ax, 1 or do something like: xor ax,ax inc ax I really need a good grade, so I'm trying to get it as optimized as possible. ( I need to optimize both time and code size)

  • How can I make my counter look less fake?

    - by Eddy Pronk
    I'm using this bit of code to display the number of users on a site. My customer is complaining it looks fake. Any suggestions? var visitors = 187584; var updateVisitors = function() { visitors++; var vs = visitors.toString(), i = Math.floor(vs.length / 3), l = vs.length % 3; while (i-->0) if (!(l==0&&i==0)) vs = vs.slice(0,i*3+l) + ',' + vs.slice(i*3+l); $('#count').text(vs); setTimeout(updateVisitors, Math.random()*2000); }; setTimeout(updateVisitors, Math.random()*2000);

  • Basic javascript function

    - by McDan Garrett
    I have this function working <script type="text/javascript"> $(window).scroll(function() { if ($(window).scrollTop() == $(document).height() - $(window).height()) { $('div#loadmoreajaxloader').show(); $.ajax({ url: "loadmore.php?wall=<?php echo $wall; ?>&lastid=" + $(".postitem:last").attr("id"), success: function(html) { if (html) { $("#postswrapper").append(html); $('div#loadmoreajaxloader').hide(); } else { $('div#loadmoreajaxloader').html('<center><font color="white">No more posts to show.</font></center>'); } } }); } }); </script> But I need to have the same stuff happening (on IOS Devices), but instead of it happening when the browser reaches the loadmoreajaxeloader div, I simply need it to happen on an onclick event on a link. Thanks heaps. Tried to add code but didn't format so here it is http://pastebin.com/p2VUqZff

  • Standardizing camera input in OpenCV? (Contrast/Saturation/Brightness etc..)

    - by karpathy
    I am building an application using OpenCV that uses the webcam and runs some vision algorithms. I would like to make this application available on the internet after I am done, but I am concerned about the vast differences in camera settings on every computer, and I am worried that the algorithm may break if the settings are too different from mine. Is there any way, after capturing the frame, to post process it and make sure that the contrast is X, brightness is Y, and saturation is Z? I think the Camera settings themselves can not be changed from code directly using the current OpenCV Python bindings. Would anyone be able to tell me about how I could calculate some of these parameters from the image and adjust them appropriately using OpenCV?

  • Python - from file to data structure?

    - by Seafoid
    Hi, I have large file comprising ~100,000 lines. Each line corresponds to a cluster and each entry within each line is a reference i.d. for another file (protein structure in this case), e.g. 1hgn 1dju 3nmj 8kfn 9opu 7gfb 4bui I need to read in the file as a list of lists where each line is a sublist, thus preserving the integrity of the cluster, e.g. nested_list = [['1hgn', '1dju', '3nmj', '8kfn'], ['9opu', '7gfb'], ['4bui']] My current code creates a nested list but the entries within each list are a single string and not comma separated. Therefore, I cannot splice the list with indices so easily. Any help greatly appreciated. Thanks, S :-)

  • How to receive packets on the MCU's serial port?

    - by itisravi
    Hello, Consider this code running on my microcontroller unit(MCU): while(1){ do_stuff; if(packet_from_PC) send_data_via_gpio(new_packet); //send via general purpose i/o pins else send_data_via_gpio(default_packet); do_other_stuff; } The MCU is also interfaced to a PC via a UART.Whenever the PC sends data to the MCU, the *new_packet* is sent, otherwise the *default_packet* is sent.Each packet can be 5 or more bytes with a pre defined packet structure. My question is: 1.Should i receive the entire packet from PC using inside the UART interrut service routine (ISR)? In this case, i have to implement a state machine inside the ISR to assemble the packet (which can be lengthy with if-else or switch-case blocks). 2.Detect a REQUEST command (one byte)from the PC in my ISR set a flag, diable UART interrupt alone and form the packet in my while(1) loop by polling the UART?

  • How to write following MongoDB query in C# Driver?

    - by user3043457
    I wrote the exact query I need in Mongo console, but I'm having trouble rewriting it in C# driver. Here's a sample of the document, it's simple dictionary: { "_id" : ObjectId("539716bc101c588f941e2c27"), "_t" : "DictionaryDocument", "CsvSeparator" : ",", "SelectedAccounts" : "0", ... } Here's the query: db.settings.find({"SelectedAccounts" :{$exists:true}},{"SelectedAccounts":1, "_id":0} ) Now, I got the first part, Find with exists working, but how to write the second parameter in C# driver? I'd just like a single string as a result, not entire document. Here's C# code I got so far: _collection.FindOneAs(typeof(DictionaryDocument), Query.Exists(key)); key in this case is "SelectedAccounts". I'd like the query to filter and return only the data I need, I don't want to return all the results and search on the C# side. EDIT: I wouldn't mind if _id was passed back, but I don't need it. So only this part would work if it could be converted in C#: db.settings.find({"SelectedAccounts" :{$exists:true}},{"SelectedAccounts":1} )

  • [Rails] HTTP Get Request

    - by Karl
    I've been trying to get Rails to play with the new Facebook Graph API. After I get the authorization "code", I need to send another request which returns the access token in JSON form. It seems to work fine, however I want to fetch the access token JSON without redirecting the user. I'm attempting to use Net::HTTP.get, but I'm not sure how to use it to get a request body, or even if it's the right thing to use to begin with. Can anyone give an example of performing an HTTP GET?

  • Need help with jQuery UI Accordion navigationFilter option

    - by theJBRU
    I'm building an accordion for navigation. Each section of the accordion has a set of links. The firing code looks like this: $(document).ready(function() { $(".selector").accordion({ collapsible: true, active: false, navigation: true }); }); This all worked fine and dandy until one of the links in each set was edited to point to a single file, call it foo.html. So now if you navigate to foo.html, the location.href matches every section of the accordion (since each section has a link to it) and that opens all the sections, defeating the purpose of the accordion. So I'm pretty sure I need to use the navigationFilter option but I've googled the living hell out of it and haven't found any examples of how to build the function associated with it. Help me, Stack Overflow!

  • Java equivalent for database schema changes like South for Django?

    - by gerdemb
    I've been working on a Django project using South to track and manage database schema changes. I'm starting a new Java project using Google Web Toolkit and wonder if there is an equivalent tool. For those who don't know, here's what South does: Automatically recognize changes to my Python database models (add/delete columns, tables etc.) Automatically create SQL statements to apply those changes to my database Track the applied schema migrations and apply them in order Allow data migrations using Python code. For example, splitting a name field into a first-name and last-name field using the Python split() function I haven't decided on my Java ORM yet, but Hibernate looks like the most popular. For me, the ability to easily make database schema changes will be an important factor.

  • Lucene .NET IndexWriter lock

    - by Pini Salim
    My question related to the next code snippet: static void Main(string[] args) { Lucene.Net.Store.Directory d = FSDirectory.Open(new DirectoryInfo(/*my index path*/)); IndexWriter writer = new IndexWriter(d, new WhitespaceAnalyzer()); //Exiting without closing the indexd writer... } In this test, I opened an IndexWriter without closing it - so even after the test exits, the write.lock file still exists in the index directory, so I expected that the next time I open an instance of IndexWriter to that index, a LockObatinFailedException will be thrown. Can someone please explain to me why am I wrong? I mean, does the meaning of the write.lock file is to protect creation of two IndexWriters in the same process only? that doesnt seems the right answer to me...

  • Update JSON file C# W8 development

    - by AndrewB
    At the moment, I've got a JSON file with content looking like this: { "username": "test", "someNumber":100 } I'm using JSON.Net to fetch the .JSON file from a webserver - C#: var http = new HttpClient(); http.MaxResponseContentBufferSize = Int32.MaxValue; var response = await http.GetStringAsync(URI); var result = JsonConvert.DeserializeObject<DatClass.Result>(response); This works great together with the class getting/setting the properties. However, what I would like to know is whether there's a good way for a user to update the .JSON file through a textbox UI? As in: [textbox - update username] [update button] - username sent to server - .JSON file updated - [textblock - showing updated username in UI]. I'm not looking for exact code solutions, I'm rather looking for good solutions on this, and/or if this is a terrible idea of an easy database(?).

  • How to get this to compile?

    I have this code which compiles and works as expected: class Right {}; class Left { public: Left& operator = (Right const&) { //... Do something ... return *this; } }; int main() { Right right; Left left; // Assign individual object -- this works left = right; } But now, this one surprises me, I thought the template would work itself out since I already provided the = operator() to the Left class. int main() { ... std::list<Right> rightLst; std::list<Left> leftLst; // Assign a list of objects -- this doesn't compile leftLst = rightLst; } What can I do so that I could convert the rightLst to leftLst conversion in a single line?

  • Creating a new buffer with text using EmacsClient

    - by User1
    I have a program that can send text to any other program for further analysis (eg sed, grep, etc). I would like it to send the data to Emacs and do analysis there. How would I do that? EmacsClient takes a filename by default, this is a data string not a file and I really don't want to create and delete files just to send data to Emacs. EmacsClient has an "eval" command-line option that let's you execute lisp code instead of open files. Is there a simple lisp function that will open a new buffer with the given text?

  • How to mark a method as "ignore all handled exception" + "step through"? Even when user has selected

    - by Wolf5
    I want to mark a method as "debug step through" even if an exception is thrown (and catched within) the function. This is because 99% of the times I know this function will throw an exception (Assembly.GetTypes), and since this function is in a library I wish to hide this normal exception. (Why did MS not add an exceptionless GetTypes() call?) I have tried this but it still breaks the code when debugging: [DebuggerStepThrough] [DebuggerStepperBoundary] private Type[] GetTypesIgnoreMissing(Assembly ass) { Type[] typs; try { typs = ass.GetTypes(); } catch (ReflectionTypeLoadException ex) { typs = ex.Types; } var newlist = new List<Type>(); foreach (var type in typs) { if (type != null) newlist.Add(type); } return newlist.ToArray(); } Anyone know of a way to make this method 100% stepthrough even if ass.GetTypes() throw an exception in debug mode? It has to step through even when "Break on Thrown exceptions" is on. (I do not need to know I can explicitly choose to ignore that exact type of exception in the IDE)
