I have tried the merge function to merge two csv files that I imported. They both have the same variable names and data types but each time I run merge all that I get is an object that contains the names of the two data frames. I have tried the following:
# ex1
obj <- merge(obj1, obj2, by=obj)
# ex2
obj <- merge(obj1, obj2, all)
and several other iterations of the above.
Is merge the correct function?
If so, what am I doing wrong?
How do I create an instance of a "labelled fields data type"?
data InputData = InputData { events :: [Event], newResources :: [Resource] }
myInputData :: InputData
myInputData = ???
Does anybody else have this same problem, when you import data from Excel file to MSSQL Server 2005, if some column contains mostly numeric data, but even if you set the column type to varchar, the wizard fails to import those fields that fail to parse as numbers?

I work for a transit agency and I have large amounts of data (mostly times), and I need a way to filter the data using two textboxes (To and From).
I found jQuery quick search, but it seems to only work with one textbox.
If anyone has any ideas via jQuery or some other client side library, that would be fantastic.
I am writing an application that needs to read a data field on another Delphi program and I do not have access to the source code of the 3rd party program. The data field contains the "foreign key" to a record I need to retrieve or create in my application.
I would appreciate any links to knowledge or components that will help me with my program.
In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack:
http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack
However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?
Another newbie question: What's the best way to store data in a Cocoa application written in Obj-C? For example if I want to create a sort of "quizzer" that quizzes the user with pre-written (and user-written) questions? How would I store these questions and answers? Core Data?
Thanks!
i am using php-openid library.
i request email address from providers(Yahoo! and Google) to return back to me to check in my tables. when the user enters user and password to get authenticated with Yahoo! or Google,the provider asks user to allow sharing info.
some think like this:
Click "Agree" to sign in to mysite.com using your Yahoo! ID and allow sharing of Yahoo! info.
You are sharing the following:
[email protected]
is it possible to skip this step?
Hi
What are the possible ways of representing data in memory in .Net (or in general)?
It would be great if data could be sorted and looked up by key (or multiple keys).
We are thinking to use collections, arrays, list of collections/arrays. One object would be in several collections (one sorted asc, other desc, etc.).
Maybe this is not a good idea, and we would like to hear some other possible solutions.
Thank you

Hi,
I have enabled the internet sharing via Airport on Mac mini successfully. I can connect to the Wifi network from my iPhone but can't browse the internet. The problem might be that the Mac mini uses a proxy to connect to the internet. Is there a way to make this work?
Question:
How to setup Internet Sharing among two computers (one Mac 10.5.6, one Ubuntu 9.10) via a router?
Situation:
The Mac is using AirPort (wireless interface) to connect to router as 192.168.1.101.
The Ubuntu is using an ethernet cable to connect to router as 192.168.1.104.
Visual:

Any ideas are greatly appreciated.
Thanks.
I bought my lil sister's netbooks for Christmas and I've been having a heck of a time trying to get Internet Connection Sharing to work.
The host computer is a Windows XP box and it uses a US Cellular 3G modem dongle thingy to set it's Internet access. Additionally I have a hard wire plugged into the LAN1 port of the router described below. (I tried the WAN port out of desperation but things didn't seem happy that way.)
Additionally they have a linksys router (can't remember specific model number, I will find this out) that I was using to take advantage of it's wireless capabilities. Originally thought about updating the router to use dd-wrt, but after reading the instructions it looked like to much of a pita (had to downgrade firmware, then install dd-wrt) to set up, eventually I caved, out of desperation, and ended up successfully installing dd-wrt on the router. I have DHCP turned off on the router, actually all I could select was DHCP forwarder.
The netbooks both have windows 7 starter installed on them.
Initially, I had the networks joined to a homegroup but I dropped that and everyone is able to see everyone in their respective network explorers.
When I turn on Internet Connection Sharing on the host, its IP on the LAN changed to 192.168.0.1, so I arbitrarily decided to assign the router to port 192.168.0.100.
When I connect the netbooks they get IPs dynamically.
As I stated before, everyone can see everyone in the network explorer, and shares can be accessed. The weird thing is that everyone can ping the router but they cannot ping each others IPs. The status on the netbooks says that there is no Internet Connectivity.
Another thing I tried was manually setting the DNS servers on the netbooks to the DNS servers that the host computer has. The funny thing is when I ping an outside domain such as google.com the IP address resolves, however I get no responses from the pings.
When I tried plugging the host into the WAN port I could ping the router, nor could I access the router's web access admin.
Another thing I tried was turning off the firewall on the netbooks and the firewall off on the host computer for the LAN connection, and they still could not ping each other. Also I thought I should be able to start a remote desktop connection but I couldn't do that either, I also checked to make sure that computers would in fact accept a request for remote desktop connections.

What is the use case for applications like PDAnet or Android Wifi Tether supporting sharing wifi over Bluetooth? A friend and I were discussing this, and neither of us could figure out why you would need to redistribute wifi over a Bluetooth connection. In most cases, said receiving device would already have wifi. Any clues would be appreciated.

Using virtualbox (win7 host, winXP guest) and a bluetooth printer (a portable one) I've set up printer sharing on host and can print from guest.
But when the host isn't connected to the internet printing stops working.
I'm using bridged adapter in virtualbox.
