Rex,

To your point regarding the modifications to par() and as you might
get more complex in those modifications, you might want to consider
"wrapping" your code within the following two lines:

op <- par(no.readonly = TRUE) 

...your code...

par(op)


This sets 'op' to contain those parameters that you might modify in
your code and then restores par() to the values that were present
prior to your manipulation. This is contained in the examples and
elsewhere in ?par.  There is a caveat in the "Note" section of the
?par help page to be aware of in this situation.

HTH,
