R help - May 2005 - making a log file with error messages?

Dear all:

Is there anyone who would help me to generate a log file reporting error
messages?

I can see error messages on the screen, but I would like to report them
as a file.

thanks

Sincerely,

cahn

One way is to define your own function to use as the "error" option
value.
E.g.

my.error.fun <- function() {
   cat(geterrmessage(), file="rerr.txt", append=T)
}

then,

options("error"=my.error.fun)
