1、安装步骤：先安装R，再安装RStudio RStudio是R的集成开发工具，本身不带R环境。 2、从当前R的官网和RStudio下载的R和RStudio的版本分别为： A .For Windows R-3.5.3-win.exe RStudio-1.2.1335.exe R-3.5.3-win.exe无论是在Win7上还是Win10上都可以顺利安装，也能正常使用，但RStudio-1.2.1335.exe在Win7上安装后，打开报错，在Win10上可以正常安装使用。 解决办法： 下载早期版本的RStudio在Win7上安装。 https://www.rstudio.org/download/daily/desktop/ 这里下载的是RStudio-1.1.462.exe 在Win7上很顺利安装，可以正常启动使用。 B.For MacOS 当前官网上下载的For MacOS的版本，RStudio无法安装在MacOSX 10.11及以下版本的操作系统里，只能安装在MacOS10.12+的操作系统里 解决办法，同样下载早期版本的RStudio，进行安装，经测试，可以正常安装和使用。 同样可从上面给的网址下载:https://www.rstudio.org/download/daily/desktop/ 来源： oschina 链接： https://my.oschina.net/u

R Sweave (Rnw) won't produce a PDF file - exit code 1

由 只谈情不闲聊 提交于 2020-12-15 05:16:32
问题 I've recently been learning how to use sweave in R to create PDF files out of Rstudio, and my machine has suddenly stopped being able to create a PDF using sweave. It can still create PDFs in rMarkdown, but it gives the exit code one when it fails to do so in sweave. There are maybe a dozen questions that I've found online that ask similar questions, but none of the answers have helped. I've tried changing the %PATH% in my environment window, I've uninstalled and reinstalled rStudio and

问题 I was doing data wrangling with Rstudio, and while I was doing something with a very large dataset, the process died. I restarted the computer, but ever since Rstudio has not been responsive or slow due to memory limits (currently, it's occupying 8gb of my 16gb RAM). I tried doing all the standard things I found on Stackoverflow. gc() and gc(reset=T) rm(list = ls()) .rs.restartR() Restart my computer.
