I cannot find in the literature a way to conduct the following t.test on 2 objects, A and B
A B col1 col2 col3 col1 col2 col3 Where col(i)'s name is identical in both A and B (they are names of tissues). How do I test (t.test) if each tissue across the object is signifanctly different?? (i'm pretty sure I have to use tapply()) Also is there a way to multi plot all 89 tissues showing the A values and the B values.. thank you ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
