Binaries updated, but not specifically for CentOS. I still get the same error about not being able to create 'R_TempDir'.

Here is the output of afni_system_check.py -check_all:

========================= summary, please fix: =========================
* login shell 'bash', trusting user to translate code examples from 'tcsh'
* have python version 3.7.4, some programs need 2.7.x
* missing R packages (see rPkgsInstall)
* insufficient data for AFNI bootcamp
