在R中检测操作系统(例如，针对自适应.Rprofile文件) [英] detecting operating system in R (e.g. for adaptive .Rprofile files)

问题描述

我想知道如何在R中自动检测操作系统，例如将内容放置在.Rprofile中.

I was wondering how to automatically detect operating system in R, for example to place things in the .Rprofile.

推荐答案

我不确定是否要使用Sys.info()，因为帮助页面上说它不是在所有R平台上都实现的；也许改用.Platform吗? ?.Platform具有很多有用的信息，因为:

I'm not sure about using Sys.info() since the help page says it is not implemented on all R platforms; maybe use .Platform instead? ?.Platform has a lot of useful information, since:

.Platform"是包含一些内容的列表 R平台的详细信息 被建.这提供了手段 编写操作系统可移植的R代码.

‘.Platform’ is a list with some details of the platform under which R was built. This provides means to write OS-portable R code.

似乎R附带的软件包比Sys.info更频繁地使用.Platform .

It also seems the packages included with R use .Platform much more frequently than Sys.info.

josh: /c/R/R-2.12.0-src/src/library
> grep ".Platform" */R/* | wc -l
144
josh: /c/R/R-2.12.0-src/src/library
> grep ".Platform\$OS.type" */R/* | wc -l
99
josh: /c/R/R-2.12.0-src/src/library
> grep "Sys.info" */R/* | wc -l
