About this notebook

ggplot2's reference page for automatic_plotting has no examples, so this notebook says only what the page describes and where Giggly stands.

The page shows how a package can make its own class of data easy to plot with three S3 generics, each a step further than the last: a fortify() method reshapes the data into a long data frame ggplot2 can use, an autolayer() method makes a layer that draws it, and an autoplot() method makes a complete plot, here from that layer. It works through a my_heatmap class wrapping a matrix, drawn with geom_raster(). Not in Giggly yet: fortify(), autolayer() and autoplot(), and geom_raster().
