[R] ordering a data.frame by average rank of multiple columns

2007-08-10 Thread Tom.O
Hi I have run into a problem and i wonder if anyone has a smart way of doing this. For example i have this data frame for 5 different test groups: Res1 <- c(1,5,4,-0.5,3) Res2 <- c(-1,8,2,0,3) Mean <- c(0.5,1,1.5,-.5,2) MyFrame <- data.frame(Res1,Res2,Mean,row.names=c("G1","G2","G3","G4","G5")
