Calculate components of box and whisker plot.

Calculate components of box and whisker plot.

Usage
stat_boxplot(mapping = NULL, data = NULL, geom = "boxplot",
  position = "dodge", na.rm = FALSE, coef = 1.5, ...)
Arguments
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
na.rm
If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.
coef
length of the whiskers as multiple of IQR. Defaults to 1.5
...
other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.
Value

  • A data frame with additional columns:
  • widthwidth of boxplot
  • yminlower whisker = smallest observation greater than or equal to lower hinge - 1.5 * IQR
  • lowerlower hinge, 25% quantile
  • notchlowerlower edge of notch = median - 1.58 * IQR / sqrt(n)
  • middlemedian, 50% quantile
  • notchupperupper edge of notch = median + 1.58 * IQR / sqrt(n)
  • upperupper hinge, 75% quantile
  • ymaxupper whisker = largest observation less than or equal to upper hinge + 1.5 * IQR
