[R] subset

[Guenther, Cameron]

Hello everyone,

I have a large dataset (x) with some rows that have duplicate variables
that I would like to remove.  I find which rows are the duplicates with
X1<-which(duplicated(x)).  That gives me the rows with duplicated
variables.  Now, how can I remove just those rose from the original data
frame.  I think I can create a new data frame without the duplicates
using subset.  I have tried:
Subset(x,!x1) and subset(x,!x[x1,])
I can't seem to find the correct syntax.  Any advice.
Thanks in advance
