On that example "nbcairo" runs almost as fast as "Xlib" on my machine (and
faster than the example runs in Windows).
This is one of the sorts of example where the planned changes for 2.8.0
will make "cairo" faster than "nbcairo".

Dear Prof Ripley,
thank you for your suggestions, they are as always very insightful!
Although, anybody can miss a point or two as I just did in namespaces.
Is the following correct?
Until redefined in the current namespace, plot.default (and all other
plot.* methods) being defined in 'graphics'
Dear knowledgeable experts :-),
I am trying to get openmpi, Rmpi and SNOW running on a Myrinet/GM

I try to load the Rmpi library and get the following:

If I run "R CMD check" on my package source directory I get no warnings
(okay, at the moment I get a few, but lets imagine for the sake of
argument I don't). Then if I run it again I get a warning about my
source package having object files in it:

Try this:
Axis.AsIs = AxisFUN = function(x=NULL, at=NULL, ..., side,
labels=TRUE) {
if (is.null(at)) at = pretty(x)
axis(at=at, ..., side=side, labels=labels, col="red", lwd=5)
}

I think that you can change the axis as a argument in plot:
custom.axis <- bquote({axis(1, col="red", lwd=5)
axis(2, col="red", lwd=5)})
suppressWarnings(plot(1:5, 1:5, frame.plot = eval(custom.axis)))
suppressWarnings(plot(1:5, frame.plot = eval(custom.axis)))

I would like to override the default way R formats plot axes with a
