There are a couple of ways but I think you need to read about R . Have a look at Managing data http://cran.r-project.org/doc/contrib/Lemon-kickstart/index.html
and / or read the Intro to R manual available on CRAN or probably from the R help icon. you have a data.frame DF you can assign names to the variables ?names names(DF) <- c("x", "y") and attach the data.frame ?attach or you can reference the columns as DF[,1] and DF[,2] --- tronter <[EMAIL PROTECTED]> wrote: > > Hello > > I have an Excel file with x-y data.
