Timesheet application for Rails
Hi all, I am looking for some time tracking software for our small company. Does anyone knows if such project on rails exists? I need simple functionality such as recording spent time for employees and managing projects or tasks. Ideally, it would be possible to integrate it into Instiki and to some existing database. There are some other solutions, but it seems to me that RoR would be ideal

RE: Is the 2.6 Linux kernel ready for production * environment
I was wondering what peoples thoughts are about this. It seem that * works just as well on Linux 2.6 as 2.4. Maybe a few small issues here and there but generally it seems to me that * is just as stable on either platform. 2.4 is the obvious choice for the highest possiblility of a stable well tested environment but 2.6 seems to have some enticing benefits. Can Linux 2.6 be considered a

Scaling in SVM
Dear Community! I'm using the svm method of package e1071 for classifying my data. This really works fine, but however I have to work after creating the support vectors and the parameters with unscaled data. So the problem is when I try to train the classifier with the option "scale=F" the result is quite poor, so training with scaled data is essential. The rescaling of the support

text works with the postscript device?
Dear R experts, R (0.63) does not seem to write me any text in a PS file. Trying x11() plot(12) text(5,5, "Hello World") works fine. Now I would like to have the same as a PS file. postscript("foobar.ps") plot(12) text(5,5,"Hello World") dev.off() Gives me a PS file with the plot -- but without the "Hello World". Why? I'm completely clueless. Ciao

use of R in big companies (references) & R-support esp in Germany
Dear R users, sorry for this general email and I am sure it has been asked way too many times. IT departements in big companies only want to support the big standards. Whatever big standards means apart from being expensive. We are in the process of trying to get a risk management project for a big conservative company in Germany. As part of the project we would use R to run simulations,

References of R in use
Dear R-users and expeRts, can anyone provide me (and others as well, of course) with reference of companies, scientific labs and/or schools where R is being used? Or does some (even unofficial) list of comanies etc. where R is being used exist? I tried to find such an information on R's homepage and on a FAQ page, but unsuccesfully. (Of course, searching through this r-help conference one

performance observation on redhat
Hi, I made an interesting observation using webservers (not just mongrel) under red hat enterprise linux ES release 4 (Nahant Update 5). Maybe this is helpful or somebody with deeper networking expertise can comment on this. Once client said that 1-2% of the response of our server were unacceptably slow (really huge 3s-21s). So I did more ab and httperf tests and notice that very few

introduction slides for beginners
Hi all, does anybody have slides for a 1 to 3 hour crash course into R, that I would be allowed to recycle to show a few people the light? On the R-website http://cran.r-project.org/other-docs.html I found several additional books, but no slides. It might be nice to add a page with slides, too. Thank you, -Armin

binary coding of NA, Nan etc.
I wonder which binary codings to use for the different "special" values used in R. I want to create binary coded files of double, int, and string values that should get read into R using readBin. Now, what is the correct way to code NA, NaN, Inf, and -Inf for these types? The documentation for read/writeBin doesnt contain any info on that ... (for int and string, there probably is only

Re: [Omega-help] RSPython_0.3.0 on FreeBSD 4.*:
Thanks for your help Duncan. Your last comment helped me to figure out what FreeBSD was doing differently than Linux/Solaris. This fix worked on a machine with Python 2.1, R 1.3.1 and FreeBSD 4.1. Here are the details: The pthreads fix: I added '-lc_r' to the PKG_LIBS definition in src/Makevars.in. The FreeBSD 'man pthread' page suggests that adding -pthread to the gcc statement

calling R from python (fwd)
A question for a (experienced) user of the RPython package on linux. I'm trying to call R from python on a linux (Suse 7.3) box.

R and Python
I am a long time user of R for financial time series analysis (xts, zoo, etc) and for my next project I am thinking of adding the Python language to the mix. The reason for adding Python is primarily its non-statistical capabilities. So my questions are what have people's experiences been with using interop between R and Python. I see there are two items, rPy and RSPython. It looks like rPy
