Interesting exchange of ideas.
A feature that should be included soon in the codebase to help in some
use-cases -- eg. handling thousand database connections on {L,W}AN.

Hello,
I remembered having seen a function tryCatch.W.E and after an online
search, found where.
It was in a R-Help post and in demo(error.catching). The question by
Marius Hofert [1] was answered, among others, by Martin Maechler [2]
which included the function tryCatch.W.E.

Dear Rui,
Thanks for this. Simon referred to demo(error.catching), and Adrian's version
returns the printed representation of the result along with messages.
Best,

Dear Adrian,
Here's my slightly modified version of your function, which serves my purpose:
--- snip ---
tryCatchWEM <- function (expr, capture = TRUE) {
toreturn <- list()
output <- withVisible(withCallingHandlers(
tryCatch(expr,
error = function(e) {
Dear John,
The logical argument capture is already in production use by other
packages, but I think this is easily solved by:
if (!is.null(output$value) & output$visible) {
if (capture) {
toreturn$output <- capture.output(output$value)
}
toreturn$value <- output$value
}
so th
Dear Adrian,
For consistency, you might want to put toreturn$value <- output$value inside of
if (capture) {}. In any event, it makes sense for me to wait for the modified
admisc::tryCatchWEM to find its way to CRAN rather than to maintain my own
version of the function.
Thanks for this,
John
