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
