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

Here is the code that I ran as R BATCH:The current implementation of try does not override the error handler setting provided in options. This will change when a more sophisticated error handling mechanism currently under development is released. For now I thnk your only option is to disable your error handler around the try. luke -- Luke Tierney University of Iowa Phone: 319-335-3386 Department of Statistics and Fax: 319-335-3017 Actuarial Science 241 Schaeffer Hall email: luke at stat.uiowa.edu Iowa City, IA 52242 WWW: http://www.stat.uiowa.edu
