Subject: methods and try() [R-devel]
Hi all, I'm having a problem with some sort of interaction with try()
and methods, I think.
The setup is as follows, I have an S4 class that holds an environment
and I would like to evaluate the right hand side of a function inside
that environment. No problem there.
However, if the formula involves a symbol that doesn't exist, which
may or may not happen, it fails as it should and reports and error
"blah blah does not exist." As it should.
When I wrap that same call in a try() statement, the error becomes "no
function to return from, jumping to top level," bypassing the try
statement and generally wreaking havoc. Any clues what might be
causing this?
