Dear R maintainer!
> User misread: it reduces the *base* cex.
It's not quite clear what the base cex is. Having read help(par), I
got the impression that it is the raw value of par(cex) as opposed to
the value multiplied by the value of cex argument which can be passed
to some functions. As you can see from my example, the value of
par(cex) is *reset*, not reduced.
> Setting a layout does reset cex.
Setting a layout using split.screen does not.
I still think it's a graphics bug, not a documentation bug. I've
attached a patch that modifies the behavior of par() and layout()
functions. Please review it and tell me in which cases the original
behavior was more appropriate.
I'm ready to provide any additional info,
Andrey
