how to overlay two histograms

Hello,

I am trying to overlay two histograms with this:

p <- ggplot(d, aes(CHR, counts, fill = name)) + geom_bar(position = "dodge")
p

but I am getting this error:
Error: stat_count() can only have an x or y aesthetic.
Run `rlang::last_error()` to see where the error occurred.

Dear Ana,

you need to specify stat="identity" [1], 
like so:

	mapping <- ggplot2::aes(
	  x=CHR,
	  y=counts,
	  fill=name)
	p <-
	  ggplot2::ggplot() +
	  ggplot2::geom_bar(
	    data=d,
	    mapping = mapping,
	    position="dodge",
	    stat="identity")

Best,
Rasmus
