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.

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

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.

old PDC, and the same domain name.

[LLVMdev] llvm-ld file not recognized: File format not recognized
Hi,
When using llvm-ld to link .bc files(compiled with llvm-gcc with option
--emit-llvm), I went into error like: file not recognized: File format not
recognized.
I was confused because llvm-ld is the LLVM linker to link llvm bitcode
files together, then why this error occurred?
I am using llvm 2.9 and the corresponding binary version of llvm-gcc.
It will be appreciated if anyone of you can
