Hi there, I donĀ“t know if you are trying to solve the delete job or to test how functions work.
If you really want to delete lines from a data.frame, try something like this. rowcount<-1:100 x<-runif(100) y<-runif(100) df<-data.frame(cbind(rowcount,x,y)) df.subset<-subset(df, !(rownames(df) %in% 1:25)) # ! (a condition) is the negation of the condition # so the output will be those lines that are not on interval 1:25 By the way, it is not a good idea to use "data" as a input argument on a function because "data" is a pre-defined function.
