If you understand the differences between R lists and R vectors then this should be easy:
> vec1 <- 1:10 > vec2 <- 2:4 > myListOfVectors <- list( vec1, vec2 ) Now you can pass the single list of 2 different sized vectors to your function. For more details on working with lists (and vectors and functions and ... ) read "An Introduction to R" which is worth a lot more than you pay for it. Hope this helps, -- Gregory (Greg) L.
