Hi, I''m working on a french website and I use the Form.serialize method to send the info through AJAX. The thing is that the accentuated letters (é,ê,à, etc.) don''t get replaced by their HTML entities and they get corrupted when retrieving the data. How could I fix that? thanks a lot, Blaise Bernie

Hello list, I've been trying to get the PostgreSQL PL/R library to compile on windows (http://www.joeconway.com/plr/). The author of this library says the problem is likely because the distributed R.dll isn't compiled as a shared dll. Is this the case? If so, is there any way to compile it such that it is shared? If that's not the case, than maybe someone on this list has a better

I'm struggling to explain an ASAN report I'm now getting that I didn't get previously on the same code. In fact the report only happens with -O2 and not when I remove the -O flags which makes it hard to debug and makes me suspect it's dependent on exactly which instructions the code generation decides to access the bytes involved. Afaict the C code shouldn't be accessing the

Hello, I've been using R embedded in PL/R (R procedural language handler for PostgreSQL, http://www.joeconway.com/plr/) very successfully for several months now. A sincere "thank you" goes to the R development team for such a great product. I have a question I'm hoping someone here can help me with. In order to get the required functionality out of PL/R, I've had to

I'm sorry if this is too off-topic--feel free to ignore. I am interested in using pl/R, an amazing "plugin" for the postgresql database. As is typical of these types of applications, pl/R needs to link against a shared library. However, it appears that the MacOS R binary does not build a static (.so) shared library. Is there an accepted, general way (read, a way that works)

Hi R-helpers Has anyone had any experience doing CGI or Servlets or using an httpd server in R? Context: we are interested in running dynamic demographic calculations on the internet (life tables, and such) in response to form submissions. I might do simple cgi to get started, but loading in data each time seems like it would be quite, quite slow. I have looked at Rserv, but I am most

Hi, I wanted to know if it''s possible to integrate FCKEditor with the inplace editor, and is it possible to have comboboxes too? If yes, could you give me some quick directions? Thanks a real lot, Blaise Bernier

Hello, we're having some problems with our dovecot setup. I've seen similar problems in the mailing list some years ago but alas wasn't able to find a solution. Our setup is as follows : An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 2.1.16). All mailboxes and indexes are on NFS and all

Sorry for the simple question: What is the "standard" package for interfacing with PostGreSQL (most up-to-date)? There appear to be at least three with different names: Rdbi.PgSQL RdbiPgSQL (available as part of BioConductor) RPgSQL (On the home page, no longer maintained in favor or Rdbi) The R and database developer page (http://developer.r-project.org/db/) was last updated in

Dear R-users, I am faced with the problem of analyzing a huge dataset (+ 2 million records, +150 variables) which does not fit into memory. I would like to know if there are pre-packaged tools (in the spirit of Insigthful I-Miner, for instance) aimed at subsampling or splitting the dataset into data-frameable subdatasets, applying functions record-wise, etc. Thank you very much for your

We have a setup in which we use PHP (with Geeklog as a CMS) as a front end to MySQL. We plan to use R for offering user driven and automated statistical analysis of some of the data we obtain. We'll be using the R interface to the MySQL database from omegahat (www.omegahat.org) for getting the data out of the database, but we were wondering if somebody tackled the problem of how to integrate

Friends I am starting on a (section of the) project where I need to build a matrix with on the order of 5 million rows and 200 columns I am wondering if I can stay in R. I need to do rollapply type operations on the columns, including some that will be functions of (windows of) two columns. I have been looking at the ff and bigmemory packages but am not sure that they will do. Before I get

Hi - I am new to RandomForest and want to be able to predict for a set of values outside of R. So for example, if I create the model in R and want to get the prediction for an observation in a database, is there a way I can get the algorithm for the trees and final prediction for this model printed out in R that I can directly implement in SQL? Or is the only way to do this is to use a wrapper

I've been studying some of the code and I'm still a little shakey on the proper method for returning a data.frame from a C function (which is my ultimate goal here). I've started some code that I've "stolen" from the archives and I'm running into crashes, etc. I've been trying to gleen some insight from the src/main/scan.c file and didn't find many comments in

Hi everybody, This may be a stupid question, but I really don't get it. When I restart my Linux box (occasionnaly / rarely), samba is not working from my Windows station. I can't connect to the samba drive. If I do /etc/init.d/smb restart, it doesn't work either. After many unsuccessfull problem determination, I found that there is two ways to correct this: 1- kill smbd -D process

Hello, The procedure for creating an import library (Rdll.lib) that is documented in gnuwin32/README.packages works fine using the i386 architecture, but it doesn't seem to work under x64. Specifically, the procedure is: pexports R.dll > R.exp lib /def:R.exp /out:Rdll.lib /machine:X86 R.dll There are two issues under x64: 1. Older version of pexports crash when applied to an x64 R.dll.
