[R] Creating data using multiple for loops

[Bert Gunter]

id <- do.call(paste0,expand.grid(0:9, 1:3, 1:5))

Comment: If you use R much, you'll do much better using R language
constructs than trying to apply those from other languages (Java perhaps?).
I realize this can be difficult, especially if you are experienced in the
another language (or languages), but it's worth the effort.
