[ESS] ess-execute and ess-command

I am constructing R expressions in elisp and evaluating them with ess-execute.
When calling ess-execute from elisp code, how can I detect if an error
occurred in R? (At the moment I can only think of something very
clumsy involving try() and writing to file).
When should one use ess-execute and when ess-command?
I don't think either of them have a meaningful return value; would it
be possible for them to return some sort of exit status?
