Importing General-Purpose Graphics in R

This report discusses some problems that can arise when attempting to import PostScript images into R, when the PostScript image contains coordinate transformations that skew the image. There is a description of some new features in the ‘grImport’ package for R that allow these sorts of images to be imported into R successfully.

本报告探讨了在将PostScript图像导入R语言时，若该PostScript图像包含使图像发生变形的坐标变换操作，则可能出现的若干问题。此外，本报告还介绍了R语言grImport包中的若干新特性，借助这些特性可成功将此类图像导入R语言环境中。
