ply_aes: Compute aesthetics groupwise

In garrettgman/ggsubplot: Explore Complex Data by Embedding Subplots

Description

ply_aes causes the aesthetics of a layer to be computed groupwise. ply_aes implements the split-apply-combine strategy of data analysis in a graphical framework. It first splits a layer's data frame into subgroups, then evaluates the layers mappings separately within each group, and finally combines the results into a single data frame which is used to build the plot for rendering.

Usage

ply_aes(layer, .vars = NULL)

Arguments

layer	a ggplot2 layer or sp_layer object. This layer's aesthetics will be computed groupwise, but the layer will remain the same in every other respect.
.vars	variable names to group by (optional), stored as a character string

Details

Users may specify which groupings to use through the .vars argument. If this argument is left NULL, ply_aes will search for and use a group aes, a glyphing or gridding criteria (in a sp_layer), a facetting criteria, or any combination of these that it finds.
