Pairwise correlation
Dear All,
I am not familiar with R yet I want to use it to perform some task, hence my
posting here. I hope someone can help.
I have a set of data, genes (rows) and samples (columns). I want to do a
Pearson correlation on all the possible pairwise combinations of all the
genes (2000). Does anyone have an idea of how to execute this in R?
Thanks in advance.

applying a formula from text
Dear Arun,
I am a novice in R bu some my friends that use R for a long time were not
able to help me. Thank you really.
Concerning your question why I need it, I think that it can be situations
where the condition, that I have to apply, depends on the data.
May be you can advice me a good text to learn programming in R.
Thank you again.

Someone needs to send network traces and debug level 10 logs
for this. And try to reproduce the same against a Windows
server.

basic sweave question
I am trying to learn the basics of Sweave so I read some things and a

[LLVMdev] DFAPacketizer with StateTrans != 0 Assertion
Hi Ivan,
The assertion was happening because I wasn't checking after the first
attempt failed. The first packet was failing and so it was ended, and
then the packetizer attempted to add it to the next packet without
checking for available resources. However this highlights probably the
real problem - my packetizer is unable to find resources for the first
instruction, or any of my
