Problem with geterrmessage()
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. Best, luke

R 3.4.3 OS X Colleagues 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. Dennis Dennis Fisher MD P < (The "P Less Than" Company) Phone / Fax: 1-866-PLessThan (1-866-753-7784) www.PLessThan.com
