摘要：Welcome to a new issue of R News, focussing on graphics and user interfaces. Paul Murell’s grid graphics system offers a modern infrastructure for R graphics. As of R-1.8.0 it is part of the base distribution but, until now, grid graphics functions could not be mixed with traditional (base) plotting functions. In this newsletter Paul describes his gridBase package which allows mixing of grid and base graphics. Marc Schwartz, known as frequent poster of answers on the mailing list r-help, has been invited to contribute to the R Help Desk. He presents “An Introduction to Using R’s Base Graphics”. The Bioconductor column was written by Colin Smith and shows a web-based interface for microarray analysis. Angelo Mineo describes normalp, a new package for the general error distribution. In the second part of my mini-series on Sweave I demonstrate how users can interact with package vignettes and how package authors can add such documents to their packages.
