Help with RStudio… I deleted the panels and don’t know how to get them back!

Hello! I am new to R and downloaded RStudio. When I was playing around with it, I managed to delete all of the other panels save one. I deleted the icon, redownloaded, and still nothing… any suggestions?

I can't see the details of your image, so this might not help. What happens if you select the menu item View -> Panes and then select Show All Panes?

If @ FJCC's method does not work try
Resetting RStudio Desktop's State.
