使用不同版本R的Rstudio项目 [英] Rstudio project using different version of R

问题描述

Rstudio可以更改其使用的R版本(

Rstudio can change the version of R it uses (https://support.rstudio.com/hc/en-us/articles/200486138-Using-Different-Versions-of-R). Is there a way to do this for a specific project?

上下文:我正在通过将R-portable与我的代码和一些其他脚本捆绑在一起来构建基于R的应用程序，以使其全部正常工作.我想在RStudio中使用应用程序中的R的可移植版本在我的项目上进行工作，而不会为我正在处理的所有其他RStudio项目更改我的R版本.

Context: I'm building an R-based application by bundling R-portable with my code and some other scripts to make it all work. I'd like to work on my project from within RStudio, using the portable version of R within the app, without changing my R version for every other RStudio project I work on.

推荐答案

这不是完整的答案，但是如果您真的想提醒您在RStudio项目中具有匹配的R版本，则可以强制停止脚本，如果版本号不匹配:

This is not a full answer, but if you really want to remind you that you have matching R version in a RStudio project, you could force the stop of the script if the version number does not match:

if (!(version$major == "3") | !(version$minor == "4.3")) { 
  stop(paste0("Version ",version$major,".",version$minor," is in use. R version 3.4.3 is required. Exiting.")) 
}

Error: Version 3.4.2 is in use. R version 3.4.3 is required. Exiting.

这将提醒您从RStudio的全局选项中更改R版本号.

That will remind you to change the R version number from RStudio's global options.
