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.

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

Processing hundreds of calls & faxes a day. No problem. If you are going to
use a Fedora box make sure you yum update right after install then the
kernel sources symbolic link is not horribly broken as it used to be.
Otherwise, just go.

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

interrupt in Linux
Does anyone know how to interrupt R in RedHat? Neither control-c nor Esc is working. What I don't want to do is close the window or kill the entire R process.

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.

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,

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 ...

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

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
