[R] detecting time out on download.file command

       I'm working with a legacy R script which makes use of the
download.file command. We're having a problem that occasionally we get a
time out from a particular FTP site but the function that does this
doesn't pass that information back to the main function that calls it.
I'm aware that it is possible to set a timeout using the options command
but I don't know how to check if a timeout has been executed. If I put
the command into a try block could I get the information there ?

All the best,
