I'm hoping you can at the same time look at the unexpected behavior I noted in a simple `plot` call that I observed over the weekend, also on a Mac, but it's hard to believe this is related to the OS..

plot(1:10,1:10, pch=20, lwd=c(1,1,1,3,1) ,type='b')

What I'm seeing is the size of the points are accepting the 'lwd' argument when my reading of the docs is that it should be the intervening segments that accept it.

And I echo Duncan's thanks.
