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

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)) where the

Does anyone know how this is don? I have a large matrix where I extract specific columns into txt files for further use. To be able to keep track of which txt files contain which columns I want to name the filenames with the column Id's. The most basic example would be to use an for() loop
