R help - Dec 2008 - passing on the ... arguments in a progammed graphics function

Hi everyone,

I want to write a wrapper function that uses the hist() function. Now I want
to allow the hist breaks argument as optional in my function. So when my
function contains the breaks argument I want the hist() function to use it,
if not, I want the hist() function to use its default for breaks.
How can I do that?

myFunction <- function(data, ...)   # breaks= as optional here
{
hist(data, breaks=???)
}

TIA 
Mark

If you make your call as

  hist(data, ...)

then a breaks arg would be passed along (as would any other).
