[R] Plotting from functions

[Yang Zhang]

I can plot to png's fine when i run this directly from the top-level
script/console:

png('diamonds.png');qplot(carat,price,data=diamonds);dev.off()

But for some reason it's not working when that's in a function:

(function(){png('diamonds.png');qplot(carat,price,data=diamonds);dev.off()})()

I suspect this is because the qplot's return value must be "returned"
to the top-level, because this works:

(function(){png('diamonds.png');qplot(carat,price,data=diamonds)})();dev.off()

Any hints on how I can plot from within a function?  Thanks in advance.
