I had succeed in installing RGUI but when I try to connect the R with Rstudio, it show me the error and I cannot solve it ，may someone help me?
This shows that you are using an old version of RStudio. Does using a more recent version help?
I have uninstalled R & Rstudio old versions, and downloaded the new versions to execute (R 4.0.3 win version, and Rstudio 1.3.1093 version). However, my RStudio is blank, I meant no consoles appeared after finishing installation. I wonder what’s wrong. Thanks for your help.
