[R] interaction of options(error=) and try()

[Vadim Ogranovich]

Dear R-Users,

I am somewhat confused by the interplay between options(error=) and try(). I
set my error handler to an expression that dumps the frames and quits. Yet,
I thought that this handler would NOT be invoked if an error happens within
try(). Apparently it was. Here is the code that I ran as R BATCH:

options(error=quote({dump.frames("t.dump", to.file=TRUE); q()}))
try({ stop("error in try") })
cat("OK\n")


And this is the log:

> options(error=quote({dump.frames("t.dump", to.file=TRUE); q()}))
> 
> 
> try({ stop("error in try") })
Error in try({ : error in try


So my question is why the error handler was invoked within try() and what do
I need to do to avoid this?

Thank you,
Vadim
