Hi, I have a function that I'm writing. The arguments in the function are as follows RFF<-function(qtype, qOpt,...){} i.e., I have two args that are compulsary and the rest are optional. Now when my user passes the function call, I need to see what optional args are defined and process accordingly...what I have so far is.. RFF<-function(qtype, qOpt,...){ mc <-

I'm a day-old R newbie (but a war-weary S veteran), with couple of first-day questions: In R 0.61, this code fails. Ops.test <- function(e1,e2) { e1 <- NextMethod(.Generic) e1 } x <- 4 class(x) <- "test" y <- x < 3 The error message is "Error in NextMethod(.Generic) : negative length vectors are not allowed.". I assume it is a bug.

Dear all, I had a R segmentation fault, and then invoked debug mode and ran step by step. When I reached "terms(Y~X1*X2*...*X16)", I would then have "segmentation" fault. However, if I just ran this under regular "R interactive" mode, it would be fine though taking long time. My questions are: 1. Is there a known limit of terms for a formula? 2. Why does the
