We briefly introduce R2G2, an R CRAN package to visualize spatially explicit biological data within the Google Earth interface. Our package combines a collection of basic graph-editing features, including automated placement of dots, segments, polygons, images (including graphs produced with R), along with several complex three-dimensional (3D) representations such as phylogenies, histograms and pie charts. We briefly present some example data sets and show the immediate benefits in communication gained from using the Google Earth interface to visually explore biological results. The package is distributed with detailed help pages providing examples and annotated source scripts with the hope that users will have an easy time using and further developing this package. R2G2 is distributed on http://cran.r-project.org/web/packages.
我们简要介绍了 R2G2，这是一个 R CRAN 软件包，可在 Google Earth 界面中可视化空间显式生物数据。我们的软件包结合了一系列基本的图形编辑功能，包括自动放置点、线段、多边形、图像（包括用 R 生成的图形），以及一些复杂的三维（3D）表示形式，如系统发育树、直方图和饼图。我们简要介绍了一些示例数据集，并展示了使用 Google Earth 界面直观地探索生物学结果所带来的即时沟通益处。该软件包随附有详细的帮助页面，提供示例和带注释的源脚本，希望用户在使用和进一步开发该软件包时能够轻松上手。R2G2 可在 http://cran.r-project.org/web/packages 上获得。
