Is there any way to include warnings in the output from capture.output? eg:
a <- capture.output(warning("test"))
all.equal(a, "Warning message: \n test ")
Conceptually, this seems like redirecting stderr to stdout, or somehow
changing warning to simple print it's output. I've had a look at
tryCatch and using a warning handler, but this terminates execution at
the warning.
Thanks,
Hadley
