二、R的发展
作为开源软件的R能够迅速发展,很大程度上取决于其活跃的社区。学习R,很大程度上也是学习各种R包的使用。截止目前(2017年3月,CRAN(Comprehensive R Archive Network)上已经有10762个可以获取的R扩展包,内容涉及各行各业,可以适用于各种复杂的统计。各地的CRAN镜像都是R网站的备份文件,内容完全一样,你可以选择离自己最近的去访问。
三、R的特长
在R官网有这样几句介绍:
R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible.
One of R’s strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed.
