Only the default error handler puts the error message in a buffer
where it can be retrieved with geterrmessage. try() replaces the
default error handler. Either look at the value returned by try() or
use tryCatch with conditionMessage.

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:
source(“USERCODE.txt”)
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)
followed by:
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.
