[R] Problem with geterrmessage()

I have a 20K line script in which I encounter an unexpected problem.
If the script detects presence of a particular file USERCODE.txt, it executes:
If that file is not present, the script executes without a problem.
There might be syntax errors in USERCODE.txt; therefore, the code above is embedded in a try command:
try(source(“USERCODE.txt", local=T), silent=T)
ERRORMESSAGE <- geterrmessage()
For unclear reasons, an earlier command is yielding an error message:
unused argument (\"\\n\")
Despite identifying the exact source of that error, I can’t fix it (and it is of no consequence).
Ideally, I would like to clear out the pre-existing error message immediately before the “try” command (or perhaps at that particular location where it is being created) — but I can’t figure out how to do so.
Any suggestions would be welcome.
