I am not able to have my r script (built in PowerBI r editor) to export to my r IDE (R Studio). Though it does open Rstudio, it does not open the editor and thus the first three lines that are supposed to be there are not there and niether is the r script itself. I am in versions: r 3.5.2 and Rstudio 1.1.419 and PowerBI 2.69.5467.2151, all 64 bit.
