patchwork

The Composer of ggplots

The 'ggplot2' package provides a strong API for sequentially building up a plot, but does not concern itself with composition of multiple plots. 'patchwork' is a package that expands the API to allow for arbitrarily complex composition of plots by providing mathmatical operators for combining multiple plots. Other packages that addresses this need (but with a different approach) are 'gridExtra' and 'cowplot'.
