Re: [R] sorting by the row names

is it possible to sort a file by the row names? I presume you mean a data frame rather than a file. In which case the answer is yes: df - data.frame(a=1:10, b=rnorm(10), row.names=sample(letters[1:10])) df[order(rownames(df)),] Regards, Richie. Mathematical Sciences Unit HSL
