Hello,
I am interested in running 3dLME to analyze our longitudinal fMRI data.
As recommended, I have installed R (3.6.0), but got several warnings/errors when I tried to install afex and phia packages.
I am wondering whether I need a higer version of R or any other system updates.
Any suggestions and thoughts would be very helpful.
Thank you!


Here are output from running "afni_system_check.py" and warnings/errors of afex/phia packages installation.
