[R] Re move row.names column in dataframe

[tonyxv]

Hello,

aa<-c(1,1,2,2,3,3,4,4,5,5,6,6)
bb<-c(56,56,33,33,53,53,20,20,63,63,9,9) 
cc<-data.frame(aa,bb) 
uniquedf <- unique(cc)
View(uniquedf)


Why does the column "row.names" appear in the new dataframe and how do I get
rid of it.

"uniquedf$row.names <- NULL" does not seem to work.

For what I'm doing this is a useless column and can cause confusion and/or
problems for subsequent merging/filtering etc.


Thanks.
