Hi,
I'm new to AFNI and I'm trying to run a 3dlmer.txt command and it kept failing like this:
Failed with error: ‘找不到‘lmerTest’所需要的程辑包‘lme4’’( means can't find the 'lme4' package that the ‘lmerTest’ needs);
Failed with error: Can't find the 'car' package that the ‘lmerTest’ needs.
I've installed rPkgsInstall -pkgs ALL, gfortran-6.1.pkg and R libraries as your website instructed, but seems to have failed to install some packages.

Can you help me out here? Much appreciated the reply!

========================= summary, please fix: =========================
* missing R packages (see rPkgsInstall)
* python library matplotlib is required
(see AFNI install docs for details)
* dot file test : want 1 modifications across 2 files:
* insufficient data for AFNI bootcamp
(see "Prepare for Bootcamp" on install pages)
