I have the latest version of R on my machine (3.6.2) and when trying to install your R essentials for SPSS (the win 64 version for SPSS v 23) it asks me to ensure this is in the folder where R 3.1 is installed. when I point it to my R installation folder (for R 3.6.2) it says R 3.1 not installed there. I could install an older copy of R as well but that seems less than optimal? Any suggestions?
