Dear Michael,
I would like to thank you for your reply. This line made things easier. One
more question what If I want to halt or pause the program when a warning
happens? Right now I get only a message printed but it would be nicer if the
execution is paused so to try to print more values.

Hi Alex,
Something like this ?
x <- 1:4
y <- list(good=2:5, bad=3:5)
for (yy in y) {
tryCatch( x <- cbind(x, yy),
warning=function(w) cat("problem values: ", yy, "\n")
)
}
