This article describes an approach to importing vector-based graphical images into statistical software as implemented in a package called grImport for the R statistical computing environment. This approach assumes that an original image can be transformed into a PostScript format (i.e., the original image is in a standard vector graphics format such as PostScript, PDF, or SVG). The grImport package consists of three components: a function for converting PostScript files to an R-specific XML format; a function for reading the XML format into special Picture objects in R; and functions for manipulating and drawing Picture objects. Several examples and applications are presented, including annotating a statistical plot with an imported logo and using imported images as plotting symbols.

继续顶，希望有朝一日，R能一统江湖

支持一下！

好东西！看一看！

R不可能一统江湖。

我常用的包是Cairo，质量很不错，能生成漂亮的png等格式图片。

请各位注意“importing vector-based graphical images into statistical software ”，就是读入软件之中，而非输出图形，但可惜的是这个包只支持PostScript, PDF, or SVG格式，我以前也见过一些包也是支持这些格式，不能不说还是有点遗憾，什么时候才会出现支持windows常见的图片格式的包啊？期待。。。
