Hi all, I am trying to call a C function from R (version 2.10.1) on a windows machine. The C code is in a .c file, I have pasted the code below although I'm very confident that it does not contain any errors (it is not my code), but also, the problem that I have occurs with every .c file that I have tried this with. I have installed Rtools and included: C:\Rtools\bin; C:\Rtools\perl;

I was previously doing an update via .rhtml templates creating an AJAX :evaluate_remote_response. I use UTF-8 in my pages, and my app requires that I be able to, say, put Japanese characters in. The problem is that when I switched this over to an RJS template it started eating the encoding. I now get garbage characters where before I got the correct ones. The code for the RHTML: <%=

Hi, This appears to be some sort of dovecot bug. When I use the -r option to recursively delete a mailbox and sub-folders, it removes the sub-folders but not the inbox.

Dear moderators, when I installed the latest version of R (R2.10.1) under Microsoft Vista (service pack 2), I ran into problems associating Rgui.exe with .RData files. On doubleckicking such files in explorer, they open in a Rterm window. Trying to associate Rgui.exe with the Rdata files via control panel / default programs does not work - Rgui is not added to the list of recommended programs. I

This is not an R question, but a question on some combinatorial mathematics. Apologies for the OT if it is wildy inappropriate. The traditional C(n.k) method tells me how many combinations k I can make with n objects. However, suppose I want the number of combinations where an object cannot be used more than Q times where Q is a parameter that changes? For instance: combn(LETTERS[1:5], 3) shows

I haven't tried it, but if snmp-ups polls every 30 seconds, and MAXAGE is 15, then with a random polling interval, 50% of the time the data would be more than 15 seconds old. In

Hi, Can someone explain the proper use of the use of perform_deliveries in the environment.rb file?? ActionMailer::Base.perform_deliveries = false I just moved a new controller to the production version of an app, but wanted to be sure everything was properly configured before sending out a big mailing, so I set perform_deliveries = false, believing that would prevent mail from being

Dear Gavin, This is really great, thank you!

Hi Railers, Does anyone have any guidance on setting up a simple way to handle product variations (e.g garment size/color)? Initially, I had thought that I would make a variation model which defined the extra bits, but it seems quite inflexible especially so if a store were to sell non-clothing items that also had variants of one flavor or another. product has_many variations title

All- Thank you in advance for any help you might be able to lend. Here is my issue. I am trying to open a fairly large .dat file.

I know that the data is "just a plain ASCII file with 720 columns and 360 rows per time step (month). It should be readable by

Hi, I''m looking at ways to encrypt email addresses rather than storing them directly in the database. There are several ways that it could be done. I could make an Encrypter class and use before_update, etc. Or I could set up an updatable VIEW in mySql. (I guess triggers might be another possibility.) However, what I would really LIKE to do is use the handy AES_ENCRYPT and
