I believe this to be deliberate. If I do
par(lty=2,lwd=3,col="blue")
plot(1:10)
I do not want the axes to be thick, dotted and blue, with black labels.
(It is also I suspect deliberate that
plot(1:10,lty=2,lwd=3,col="blue")
does not pass any of those parameters on to axis().)
You say you made the labels bigger: to do that you needed to set cex.axis
and cex.main, not cex.
I'm afraid this change would break a lot of existing code. I am aware
that S-PLUS does this (with blue labels too), and I have always found it
irritating to have to work around it.
