log_close | R Documentation |
The log_close
function closes the log file.
log_close()
The log_close
function terminates logging. As part of the termination
process, the function prints any outstanding warnings to the log. Errors are
printed at the point at which they occur. But warnings can be captured only
at the end of the logging session. Therefore, any warning messages will only
be printed at the bottom of the log.
The function also prints the log footer. The log footer contains a date-time stamp of when the log was closed.
