#####list of differentially expressed genes########## > probe.names<- + all_differ[[2]][all_differ[[1]][,"BY"]<=0.01] Error in all_differ[[1]][, "BY"] : incorrect number of dimensions Hi, I am pretty new with R. What i am trying to do is to find all differentially express genes and list of differentially expressed genes. Am i doing something wrong? I keep getting incorrect number of dimensions. How do i find out the correct dimensions? thanks, Keizer -- View this message in context: http://www.nabble.com/Newbie%3A-Incorrect-number-of-dimensions-tp15773090p15773090.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
