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.

I have written full examples, and tested then under R 0.90.1, both by entering example() for each function and R CMD check, both of which worked without problem. Under

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
