PLEASE do your homework as the posting guide asks. 1) A factor is not a vector: try is.vector on one. 2) levels(x) is not the `values' of an factor object. To transfer it to VBA you need to coerce it to character -- at that *is* in the FAQ. 3) Once you know you have a vector, typeof() will tell you which of the 7 types it is. (logical, integer, double, complex, character, raw, list) But you need to test first. Most R objects are not vectors, or not just vectors. -- Brian D.
