[R] error message for every parenthesis

I seem to be having the same problem Garrett (below) had in 2009.
However, I do not have functions named try written in my active code.
In fact, I don't have any of my own functions written at all yet.  I
did just install version 3.2.1 today, and the errors started after
that.  Please advise!

Thank you,

Tara Kerin

An example from my GUI is below:

[Workspace restored from /Users/tarakerin/.RData]
[History restored from /Users/tarakerin/.Rapp.history]

Error in try(gsub("\\s+", " ", paste(capture.output(print(args(library))),  :
  unused argument (silent = TRUE)
> library()

Presumably this has something to do with command completion or argument
hints.  From the "silent = TRUE" error, and your example, I would guess
you have a function named try(), and the GUI is finding yours instead of
the one in the base package.

The GUI shouldn't do that, it should look in the right place, but as a
workaround, you could remove your function named "try", and call it
something else.
