  There appears to be a mismatch between the documentation and behavior of
title(), or at least a clarification is in order.  The documentation says
you can pass extra arguments from par() as "...".  However, cex at least
is ignored. Later on in the documentation it becomes clear that you can
specify these extra parameters as part of a list.

  I wouldn't say this is necessarily a bug (and there's certainly a way to
do what you want, if you read the rest of the documentation), but I will
say it didn't seem to follow the same conventions as most of the rest of
the graphical annotation in R.  I would have expected
title(main="foo",cex=2) to set the title larger ...

  I think it would be nicer if title() worked this way, but if it doesn't
it would be nice to have an additional note in the documentation for "..."
to the effect that parameters such as cex, col, etc., should be set using
the list mechanism described below.

## setting parameter with par(): works
for (i in 1:9) {

## passing parameter as part of a list: works
for (i in 1:9) {

## passing cex as an additional arg: doesn't work
for (i in 1:9) {
