Hi, I have a question about cummeRbund package. I upgraded my R and cummeRbund to 2.15 and 1.2 respectively. ever since when I run the following commend I get an error. > cufdat2b=readCufflinks('diff_out_2b/') > csVolcano(genes(cufdat2b),'C','P') Error in eval(expr, envir, enclos) : object 'log2_fold_change' not found other plots work find. what could I do to fix this? Thank you.
