I have a dataframe consisting of factors in one column. Im trying to remove certain levels using the following code: toBeRemoved1<-which(DATA$UnitName_1=="lake") DATA<-DATA[-toBeRemoved1,]
However it will not remove the level "lake" In the past this worked for me, but its not working now. Any help appreciated.
