Plotting from functions
Hi, Within functions, you often do need to wrap the plotting calls in print() (you would see this if you read the FAQ). Cheers, Josh

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.
Actually, just found that things work if I do: print(qplot(...)) Is this just what you need to do to plot from within functions?
