Rstudio 非常缓慢 [英] Rstudio is painfully slow

问题描述

突然，Rstudio 慢得令人痛苦，现在无法使用.这意味着，我打开它，如果我输入任何内容，会有几秒钟的延迟.我已经探索了我能想到的所有选项:1. 重新安装 R 和 Rstudio(虽然我不是 100% 确定我可以删除所有组件)，2. 尝试重置设置.... 显而易见的事情，例如清除工作区和控制台.

Suddenly, Rstudio is painfully slow, and now it is unusable. This means, I open it up and there is a lag of several seconds if I type anything. I have explored all the options I can come up with: 1. re-installing both R and Rstudio (although I am not 100% sure I could remove all components), 2. trying to reset settings.... the obvious things such as clearing the workspace and the console.

我的数据大小可以忽略不计.我想不出别的……有什么想法吗?

The size of my data is negligible. I cannot think of anything else.... any ideas?

我唯一能做的表明配置可能有问题的观察是(有时)，我将gctorture false"视为环境中的一个值.

The only observation i can make that shows something could be wrong with the configuration is (sometimes), I see "gctorture false" as a value in the environment.

推荐答案

只是猜测，但 ?gctorture 说

Just a guess, but ?gctorture says

 Provokes garbage collection on (nearly) every memory allocation.
 Intended to ferret out memory protection bugs.  Also makes R run
 _very_ slowly, unfortunately.

这听起来很适合您的问题！你可以试试

which sounds about right for your problem! You could try

gctorture(FALSE)

如果这加快了速度，那么寻找可能已经设置的地方，例如，在 .Rprofile(当前工作目录，或您的用户主目录，或 R 的安装目录；请参阅 ?.Rprofile) 并确保您启动 R 没有加载任何 .Rhistory 或 .RData 文件(再次在工作目录、您的主目录等中)

If that speeds things up, then look for somewhere that this might have been set, e.g., in a .Rprofile (current working directory, or your user home directory, or the installation directory of R; see ?.Rprofile) and make sure that you start R without loading any .Rhistory or .RData files (again in the working directory, your home directory, etc.)
