Hello!
I am having issues trying to plot to a ong (or jpg) when the R-code in a
bash script is executed from cron.
I can generate a pdf file, but when I try to write to a png, the file is
created, but nothing is written. If I execute the bash script from my
console, everything works file. Any
() but uses bitmap(),
which in turn uses postscript-to-png via ghostscript. BTW, personally
I think PNGs generated via bitmap() look way better than the ones
generated via png().

Hello everyone,
We have started a very small R study group here in Berlin, Germany.
Since we're all relatively new to R we are using 'Using R for
Introductory Statistics' by John Verzani (one used that at a course
once).
Is there anyone who have exercisers fitting for group discussions,
Hi all,
I have a data frame with some measured values of some animals. Sometimes the
measurement failed, resulting in a NA for a measurement and sometimes the
animal died, resulting in NA for all measurements.
I have several groups of animals. How do I find the size of each group with

Dear all,
I want to see if the treatment of an animal with a specific compound has an
effect on the expression of certain genes. Though my question is based in
biology, it really is all about how to deal with the standard deviation in
normalised data.
I have three groups of animals; untreated,

In that case, I would _strongly_ advise that you get advice from a
local statistician.

Hello all,
I have some histograms of amount of DNA in some cells (DU145 cells
overexpressing Bax and Bcl-xL for those who wish to know). The histograms
show not only two peaks as expected, but three, indicating that some cells
have more than normal amounts of DNA.
I am interested in knowing how
