Dear all, I use the R R Under development (unstable) (2011-09-28 r57099).

When I load the RQDA package, it issues warnings. As the RQDA package
developer, what should I deal with such message? Thank you very much.
Loading required package: gWidgets
Loading required package: DBI
Loading required package: RSQLite

Use 'RQDA()' to start the programe.

Don't attempt to change variables in other packages.  Something that 
RQDA is doing is attempting to change stockIcons and updateStockIcons in 
the gWidgetsRGtk2 package.

Duncan, thanks very much.

Yet, I don't recall I attempt to change any thing in the
gWidgetsRGtk2. Is there a way to trace what part of the code is trying
to do so?

Thanks.

So take a closer look at your .onAttach.

In fact it is gWidgetsRGtk2 that is using assignInNamespace, and you 
are running that in your startup code.  assignInNamespace was never 
intended to be used in production code, and John Verzani's packages 
need to be re-designed to respect the integrity of their namespaces.

Startup hooks was also not designed to be used to run large chunks of 
code, and as they are run under tryCatch they can be difficult to 
debug.
