stat_boxplot. ggplot2 0.9.3.1

Usage

stat_boxplot(mapping = NULL, data = NULL, geom = "boxplot", position = "dodge", na.rm = FALSE, 
  coef = 1.5, ...)

Arguments

coef: length of the whiskers as multiple of IQR. Defaults to 1.5
na.rm: If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.
mapping: The aesthetic mapping, usually constructed with aes or aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
data: A layer specific dataset - only needed if you want to override the plot defaults.
geom: The geometric object to use display the data
position: The position adjustment to use for overlappling points on this layer
...: other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.
