making a data frame containing the gene expression data from different origins

Hi

I would like to know how to make a data frame containing the gene expression data from different origins as each of its rows corresponds to a gene, and each of its columns corresponds to a sample? I am new in R so any suggestion for R scripts is highly appreciated. Thanks a lot in advance.

Dear Pgibas

Thanks for your consideration. My input is different .cel files obtained by different researchers. Indeed, I want to perform a meta-analysis of differentially expressed genes on three affymetrix data.

.cel files are to be read through affy package in R.

You could also look at the Biostars tutorial Analysing Microarray Data In Bioconductor

Please do a good internet search, before posting any question.

Also, there are several tutorials available over internet.

I will also suggest reading the R manuals.
