Change default number of tiles in stat_density2d

[K P]

I'd like to change the number of tiles or bins. It appears 100 is the default.

I've tried this:

c + stat_density2d(geom="tile", aes(fill = ..density..), bins = .05, contour = FALSE) + xlim(1,10) + ylim(1,10) 

c + stat_density2d(geom="tile", aes(fill = ..density..), binwidth = .05, contour = FALSE) + xlim(1,10) + ylim(1,10) 

But neither changes the plot. Any ideas?

Thanks.

Hi Kenton,

It looks like "n" works to indicate the number of bins ...

ggplot(mtcars,aes(carb,gear))+stat_density2d(geom="tile",aes(fill=..density..),n=10,contour=FALSE)

Yes. Perfect. Thank you. Just out of curiosity: do you know if there is an upper limit? It will do more than than the default 100 (which is great for me) but not 1000.

I'm not sure. My guess is if there is a limit, it's not self-imposed. I was able to do 1,000 on the cars data set, but not on the diamonds data, because of memory.
