It appears that the package widgetTools (which is called by affy) tries to
check if it is under GUI mode or not before adding a Vignette tab to the
GUI menubar.  However, the current check that it is using is
if(interactive), which is still TRUE even in Rterm.  We're looking at
finding a mechanism to detect if it is inded Rgui instead of Rterm ...
