Sort or Permutate
Hi,
You can also use:
within(small,{order(value)})
#?????????????????????????? file.name???? value
#1???? /storage/storage0/59Off.Rtable 0.2203863
#3 /storage/storage0/5912314ff.Rtable 0.2886594
#2??? /storage/storage0/5912On.Rtable 0.4052370

I do not quite undestand how one can complete this task in R. Could you please spend some time helping me?
Please provide data using dput. You can do it using order() like this small <- data.frame(file.name=c( "/storage/storage0/59Off.Rtable", "/storage/storage0/5912On.Rtable", "/storage/storage0/5912314ff.Rtable"), stringsAsFactors=FALSE, value=c( 0.220386301811093, 0.405237035258638, 0.288659374128626) ) v.index <- order(small[,"value"]) small <- small[v.index,] small Berend ______________________________________________ R-help at 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.
