If you are using the "$" function, you do not have an array but rather a dataframe. The distinction in R is not at all trivial. If this is a dataframe and you are only woring with one column then this might work (assuming that thememetsCopy alreadyexists) : mesmentsCopy$V1 <- 100*quantile(mesments$V1, (1:100)/100) All untested. You were asked in the Posting Guide to present a means of creatine data that has the same structure. Using dput is a good way of presneting htat structure in ascii form. > > would become: mesmentsCopy$V1: 50, 100, 0 > > The actual array has many more rows and columns, of course. > > Cheers, > > Greg Allen > Freelance Techno-Slave > SLC, Utah > > ______________________________________________ > R-help@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.
