short-hand to avoid use of length() in subsetting vectors?
...'m seeking a short-hand for referring to the length of vector one is trying to index.
E.g., for a data.frame, say,
> test.frame <-data.frame(matrix(c(1:100),ncol=10,nrow=10,byrow=T))

that would allow one to avoid the "(length(some.dataframe$variable)-offset)"?
I was thinking something paralleling the use of negative indices in [?] might exist with seq(from,to), e.g. for the above
> test.frame$...
