StatEllipse: Generic ggplot biplot function

In low-decarie/ggpca: Creates ggplot biplot methods for pca objects

Description

Produces a ggplot biplot from an PCA analysis similar to biplot. Currently has methods for princomp and prcomp.

Usage

StatEllipse

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.
stat	The statistical transformation to use on the data for this layer.
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 biplot for more details.

Format

proto object 
 $ calculate_groups:function (., data, scales, ...)   
 $ objname         : chr "ellipse" 
 $ default_geom    :function (.)   
 $ calculate       :function (., data, scales, level = 0.75, segments = 51, ...)   
 $ required_aes    : chr [1:2] "x" "y"

Examples

p <- qplot(data=iris,
           x=Sepal.Length,
           y=Petal.Length,
           colour=Species)
p <- p + stat_ellipse()
print(p)
