Just to add to Thomas Lumley suggestion: it's generally a good idea to call a wrapper function it by a different name.
This is generally good advice. However, if you want your graphics device started automatically when you plot, it either has to have the same name as the usual default device or you have to also set options(device="myX11")

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.
