How do I change the kernel bandwidth used in a density plot in R
stat_geom utilises the
adjust argument to apply a multiplier to the optimal bandwidth that ggplot calculates see documentation for
ggplot(mtcars,aes(mpg))+geom_density() + stat_density(adjust = 2)
I gather to determine the calculated optimal bandwidth - based on "the standard deviation of the smoothing kernel" - you'll need to interrogate Venables, W. N. and Ripley, B. D. (2002) Modern Applied Statistics with S. New York: Springer.

How do I see what bandwidth gets used for kernels in a density plot and how do I specify a bandwidth to be used? I tried
with no luck.

?stat_densitywhich in turn points you to
