Adjust hexbin legend breaks


In this example of a hexbin plot, the legend on the right has 10 levels/classes/breaks. Does anyone know how to change the number of levels? Say I want to change it to 5 or something.

library(hexbin) x=rnorm(1000, mean = 50, sd = 1) y=rnorm(1000, mean = 30, sd = 0.5) df <- data.frame(x,y) #plot(df) hb <- hexbin(x=df$x, df$y) #hb <- hexbin(x=df$x, df$y,xbins=30) #plot(hb) gplot.hexbin(hb)

And here's approximately the same thing using ggplot.

library(ggplot2) ggplot(df, aes(x,y))+ geom_hex(aes(fill=cut(..value..,breaks=pretty(..value..,n=5))),bins=15)+ scale_fill_manual("Count",values=grey((5:0)/6))
