ymax error with stat_bin

Why am I getting this ymax error when doing the following graph in ggplot2? I am trying to create a histogram with some data labels.

require(ggplot2)
df=data.frame(ToothGrowth)
ggplot(df,aes(x= len))  + 
  stat_bin(geom="bar", binwidth=5, aes(fill=..count..), colour="black") + 
  stat_bin(binwidth=5, geom="text", aes(label=..count..), vjust=-1.5) +
  facet_grid(.~supp)+
  ylim(c(0,15))+
  theme_bw()

Can someone explain to me what the ymax parameter is too?

This can be fixed by doing:

ggplot(df,aes(x= len, ymax=max(..count..)))  + 
  stat_bin(geom="bar", binwidth=5, aes(fill=..count..), colour="black")

So by putting the ymax parameter in the aes and setting it to ..count.. in the situation where you are using stat_bin.
