Exclusion of elements in a vector
Try this: vector[ setdiff(seq_along(vector), as.numeric(idx)) ] where idx is your vector of indices to exclude, e.g. idx <- 3:4 idx <- numeric(0) idx <- NULL The last one gets converted to numeric(0) by as.numeric so it still works. On Thu, Sep 25, 2008 at 7:43 AM, Stefan Fritsch

Dear R Users, I want to exclude elements in a vector by: vector[-exclude] is it intended to cause an error if no elements are excluded?
vector <- 1:10 exclude <- NULL vector[-exclude]
Error in -exclude or am I just definig exclude wrong, if no elements should be excluded? with kind regards, Stefan Fritsch
