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]
