In my R Studio, I once plotted a certain function. I deleted R and R Studio and reinstalled it. I made a new Working Directory, cleared the session, looked out for unwanted things in the WD, inspected search paths, checked for auto loading scripts and searched for hidden files. If im plotting a function now, still the once plotted functions shows up. I don't know how this is possible and need help.

and I think the graph refers to a Shapiro Wilks test I once performed

It's possible that the previously plotted function is still showing up in your R Studio environment because it's cached or stored in a temporary location. This can happen even if you've deleted R and R Studio and reinstalled them, as the caching mechanism may still retain the function data.
