Hi
Are all your input p values the same? If so your output FDR values would be the same. Or are all your p-values relatively large? Then (nearly) all your FDR values might be 1. Why don't you put a small example up of what you did? Then we could see what method you used etc. Regards JS --- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of A Ezhil Sent: 10 July 2008 15:41 To: r-help@r-project.org Subject: [R] false discovery rate ! Dear All, It is not a typical R question (though I use R for this) but I thought someone will help me. For the list of P values, I have calculated FDR using p.adjust() in R (bioconductor). But my FDR values are same for all the P values. When do we get same FDR values? Does the smallest P values should less than 1/N? (where N is the number of P values) Thanks in advance.
