Bin data
stat_bin(mapping=NULL, data=NULL, geom="bar", position="stack", width=0.9, drop=FALSE, ...)

Missing values are currently silently dropped.
This page describes stat_bin, see layer
and qplot
for how to create a complete plot from individual components.
A layer
The following aesthetics can be used with stat_bin. Aesthetics are mapped to variables in the data with the aes
function: stat\_bin(\code{aes}(x = var))
x
: x position (required)
y
: y position

## Not run: m <- ggplot(movies, aes(x=rating)) m + stat_bin() m + stat_bin(binwidth=0.1) m + stat_bin(breaks=seq(4,6, by=0.1)) # See geom_histogram for more histogram examples # To create a unit area histogram, use aes(y = ..density..) (linehist <- m + stat_bin(aes(y = ..density..), binwidth=0.1, geom="line", position="identity")) linehist + stat_density(colour="blue", fill=NA) # Also works with categorical variables ggplot(movies, aes(x=mpaa)) + stat_bin() qplot(mpaa, data=movies, stat="bin") ## End(Not run)
