[R] par specification inside formula vs. outside function call

The other day I asked a question about changing the size of axis labels
in a dotchart.  Chuck Cleland provided the answer, which was to specify

par(cex.axis = .8)
outside the call to dotchart

I had tried this inside the formula, and it did nothing (nor did it
produce an error).

I was wondering when it is necessary to specify things outside versus.
inside a call to a function

Thanks
