Dear All, I am analyzing the miRNA data set in which I have 817 unique probes for each they have 20 features each . I have to group the similar features and take the median across them so that I have a data with no repeats to perform invariant analysis .
My data looks something similar format probename sample1 sample2 sample3 A 2.3 2.4 2.5 A 8.9 3.6 7.9 A 4.7 4.4 2.2 C 2.2 2.1 2.3 C 1.3 1.3 2.9 B 2.2 2.1 2.7 B 2.2 2.1 2.8 I want to get some thing like after the means for similar probename are calculated A 2.3 2.4 2.5 B 8.9 3.6 7.9 C 2.2 2.1 2.8 I have to group the probename elements and and get median across them. Please help with this so that I can get complete my analysis . -- Thanks Hari 215-385-4122 "If there is anyone out there who still doubts that America is a place where all things are possible" -- Thanks Hari 215-385-4122 "If there is anyone out there who still doubts that America is a place where all things are possible" [[alternative HTML version deleted]] ______________________________________________ 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.
