[Rd] calling browser on error
Dear R-developers,
I am trying to figure out a way to call browser() when an error occur, and
naturally I want the browser() to be called in the environment of the error.
I tried something simple in vain:
f - function() { x - 1; stop('ok') }
tryCatch(f(), error=browser())
Called from: tryCatch(f(), error = browser())
## if browser() was called in the local environment of f then 'x' would be set,
but it's not
Browse[1] x
Error: object 'x' not found
Browse[1] Q
Is there a way to make it work? What do people do to 'set an on-error
breakpoint'?
Thanks,
Vadim

Re: [Rd] calling browser on error
I believe options(error=recover) will do what you want.

Re: [Rd] calling browser on error
Joshua,
I didn't know about 'recover', thank you!
Anyway it doesn't work for me:
tryCatch((function() { x - 1; stop('ok') })(), error=recover())
Enter a frame number, or 0 to exit
1: tryCatch((function() {
Selection: 1
Called from: eval(expr, envir, enclos)
Browse[1] x
Error: object 'x' not found
Browse[1] Q
Though it does work if I set options(error = recover):
options(error = recover)
(function() { x - 1; stop('ok') })()
Error in (function() { : ok
Enter a frame number, or 0 to exit
1: (function() {
Selection: 1
Called from: eval(expr, envir, enclos)
Browse[1] x
[1] 1
Browse[1] Q
I do not run the latest R so it might be the reason:
version

platform i386-pc-mingw32
arch i386
os mingw32
system i386, mingw32
status

minor 9.1
year 2009

Re: [Rd] calling browser on error
He said to use options(error=...) instead of
tryCatch(error=...). In C++ lingo, the handler
set by options(error) is called when the exception
is thrown while tryCatch's handler is called
when it is caught.

withCallingHandlers is another option.
