Either delete the spaces in the car names, or use sep=\t

Isn't it possible to tell the isoMDS function that it should ignore doubled

Thanks Marc. The information is in help(Memory-limits).
We are aware that at some point we will need to raise this limit and have
discussed ways to do so. But it is not going to be an issue for a while:
working with 16Gb objects needs the sort of amount of memory that will not
become common
That two distances are the same is *not* what the message says.
You can't just look at elements of the results of dist() and simply relate
them back to object numbers. Try as.matrix(x.dist) for a human-readable
form.

It certainly runs under Windows terminal services. Since it is just a
standard Windows application I see not reason why it should not run under
Citrix, but have no first-hand experience.

Such things are hard to do from R level, hence the use of match.call to do
it at C level.

Why not plot directly to a bitmapped format, using bmp() or png()?
That way you can create a large 'display region' when you open the device.
BTW, I guess you are on Windows but you did not say so: bmp() only exists
on Windows.
