Just to add to Thomas Lumley suggestion: it's generally a good idea to call
a wrapper function it by a different name. This way, when you forget that
you have a wrapper function, you won't be puzzled by why the function
doesn't behave according to the documentation, and you won't embarrass
yourself by asking other people why there is a bug in R. Also, if the
function is called programmatically by other functions, those usages might
be depending upon the standard defaults being in effect. So, just do
something like:
myX11<-function(display="",width=2,height=2,...){
grDevices::X11(display=display,width=width,height=height,...)
}

You can write a wrapper
X11<-function(display="",width=2,height=2,...){
grDevices::X11(display,width,height,...)
}
and put that into your Rprofile.
