deleting/removing previous warning message in loop
Hello R Users,
I am having difficulty deleting the last warning message in a loop so that the only warning that is produced is that from the most recent line of code. I have tried options(warn=1), rm(last.warning), and resetting the last.warning using something like:
> warning("Resetting warning message")
This problem has been addressed in a previous listserve string,
