So, i've been writing code in R interfacing with mysql, its been fun

documentation has been useful, learning quite a bit.
the only annoying thing i've been encountering is while coding/
debugging, my
session gets clogged, especially with sql connections. At the end
of the
code i dbDisconnect, but when the script is stopped by an error, the
session
stays open.
Usually i'll remember to ls() and dbDisconnect at console manually,
though,
sometimes I forget and wind up with a bunch of extra connections.
A couple of questions:
First: is there a way to tell R to execute some commands before
dumping back
to console on error,
?options
error:
either a function or an expression governing the handling of non-
catastrophic errors ....<snipped rest of paragraph>
and/or
second: is there a way to capture error messages and continue
executing?
?try
Sorry if this has been addressed already, but, even aided by the new
awesome
google i haven't been able to find it.
