This makes it appear that you expect this to be done in ggplot2 automagically. I suspect you must instead first find the right approach to construction of those upper and lower bounds before plotting. It's not clear what methods you expect to be needed. Your desperation is not a guide. Perhaps trying a bit of searching?

install.packages("sos")
library(sos)
findFn("confidence intervals density estimates")


Delivers quite a few results. Then searching on the text within that webpage you find 


208	2	27	54	nprobust	kdrobust	2016-11-14 16:41:50	27	Kernel Density Estimation with Robust Confidence Intervals
209	2	27	54	nprobust	lprobust	2016-11-14 16:41:50	27	Local-Polynomial Estimation with Robust Confidence Intervals

Is that what you seek?

I know you just subscribed, so now is the time to read the Posing Guide.
