According to the documentation, the scaling parameter 'cex' is callable

Which documentation? It is not mentioned on ?plot. ?plot.default says
'cex' a numerical vector giving the amount by which plotting text
and symbols should be scaled relative to the default. This
works as a multiple of 'par("cex")'. 'NULL' and 'NA' are
equivalent to '1.0'.
so note that this is an argument (not a par), a vector not a scalar and of
limited scope ('plotting' does not include annotation).
Not that not all plot() methods call plot.defualt(), so there is no
statement that I can see that all plot() calls will make use of an in-line
'cex' argument.
If I set cex using par(), the graph parameters scale appropriately.
Is this a bug, is it a Mac-only (quartz) bug, or something else?
We need a reproducible example of what does not work. It is very unlikely
to be a quartz() bug, as all this is controlled in the base graphics
subsystem. Before calling 'bug', please have the courtesy to lay out the
evidence carefully.
