Appending diagnostic information to all lines sent to stdout and stderr
...using sink()
I would like to append extra information such as "date", "memory
usage" etc to every line of output that goes to stdout or stderr.
For example
> cat("hello \n")
should give output that looks something like:
"hello --- Thu Jun 19 18:39:15 2008 | cel_norm_expm | 389.6 Mb used |"
instead of just:
"hello"
I don't want to replace functions like "print", "cat", "stop" and
"warning" with my own special functions.
Instead, I want to somehow catch the messages that these functions
return and alter them...
