I am relatively new to R, and am having a problem with the following snippet of code, and I do not at all understand why it is behaving this way. I am running Windows XP, with R 2.12.1.I copy and paste these 4 lines into the R Console: t<-c("a","b","c") ans<-select.list(t) txtNBS<-winDialogString("NBS","300") choose.files() I click on OK in the Select One dialog, and on OK in the Question dialog, and then Cancel in the file dialog. Everything behaves as I expect it to. (All 3 of those dialog functions are in the utils package.) I then copy and paste these 6 lines defining the function fn, into the R Console. Note that the body of the function is exactly the same as the 4 lines above that worked well. fn<-function() { t<-c("a","b","c") ans<-select.list(t) txtNBS<-winDialogString("NBS","300") choose.files() } When I then invoke this function by typing fn() into the R Console, I again click OK in the Select One dialog, and on OK in the Question dialog. BUT, the file dialog never appears. Furthermore, if I then type choose.files() into the R Console, about half the time the file dialog appears and about half the time it doesn't. Any help anyone can give me is much appreciated. I cannot see what I am doing wrong here.
Looks like a bug in one of those functions. I'll look into it.
