Hi
I downloaded both Install R and Install RStudio exe files .When I run the program :
1-I selected the English as language choice but after the installation completed (RGui) the language in console is in Turkish.Some letters are missing in Turkish words.
2-How do I add some extra packages like mfilter package ?I can not find the right button?
3-How do I add Source pane Console pane Environment pane Output pane?Where do I click again to add these panes?Thank you
Your image shows the R GUI. That is different than RStudio. Look for RStudio among your available programs and run that.
