Hello,
You can trap errors with ?try or ?tryCatch.
Example:
result <- vector(mode = "list", length = 5)
for(i in 1:5){
result[[i]] <- tryCatch(if(i == 3) stop("This is an error") else 2*i + 1,
error = function(e) e)
}
result
for(i in seq_along(result)) {
err <- inherits(result[[i]], "error")
print(err)
}
Hope this helps,
Rui Barradas

What is the recommended way to trap errors in R? My main need is to be able to
trap an error and then skip a section of code if an error has occurred. In VB
for Excel I used the “On Error goto .....” construct to do this.
