摘要：The grid graphics package (Murrell, 2002) is much more powerful than the standard R graphics system (hereafter “base graphics”) when it comes to combining and arranging graphical elements. It is possible to create a greater variety of graphs more easily with grid (see, for example, Deepayan Sarkar’s lattice package (Sarkar, 2002)). However, there are very many plots based on base graphics (e.g., biplots), that have not been implemented in grid, and the task of reimplementing these in grid is extremely daunting. It would be nice to be able to combine the readymade base plots with the sophisticated arrangement features of grid. This document describes the gridBase package which provides some support for combining grid and base graphics output.
