Hello, ? I am a R-beginner and I need some help.?The question is very simple: I need to do a pearson correlations (r,p-value and FDR with BH) from an Expression array (with several thousand genes for lets say 20 cell lines)?with some features of those cell lines. My problem I have is the organization of the excel sheets and how to introduce the data into R and run the script. I though the easiest and more organized for me would be two expcel sheets: 1- Only Expression data (in rows the?genes and in colums cell lines) 2- Only the features (In row the features (e.g. a) growth rate, b) sensitivity to some drugs) and in columns the cell lines). -->That would creat both sheets with 20 colums. Now I would like to get a correlation of the gene 1: the expression of all lines with the growth rate. the same for gene2... and soforth. I sould obtain as many r,p and BH(FDR) as genes there are. the same I would need to do for the sensitivity... and so on. Do you think this is doable? I am not at all a bioinformatic expert, so all help is very welcome. Thank you very much!
