Dear AFNI users,

I am trying to run ANOVA using 3dMVM. When I run the script I get, the following error:
updating R_LD_LIBRARY_PATH ...
Loading required package: lme4
Loading required package: Matrix
Error: package or namespace load failed for ‘afex’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘data.table’
Execution halted

I am using R 3.6 in MacOS Catalina (vesrion 10.15.6). When I re-install R packages (rPkgsInstall -pkgs ALL) I get the following error :

Warning messages:
1: In install.packages(pkgs_miss, dep = TRUE, repos = site) :
installation of package ‘data.table’ had non-zero exit status
2: In install.packages(pkgs_miss, dep = TRUE, repos = site) :
installation of package ‘Rmpi’ had non-zero exit status
3: In install.packages(pkgs_miss, dep = TRUE, repos = site) :
installation of package ‘gsl’ had non-zero exit status

Then I tried to install just data. table using rPkgsInstall -pkgs data.table.

I again get the same warning message:

Warning message:
In install.packages(pkgs_miss, dep = TRUE, repos = site) :
installation of package ‘data.table’ had non-zero exit status


Following is the AFNI check message afni_system_check.py -check_all:

========================= summary, please fix: =========================
* just be aware: login shell 'sh', but our code examples use 'tcsh'
* shell sh : found login shell setup file .profile
* OS X version might be old
* consider setting DYLD_LIBRARY_PATH to /opt/X11/lib/flat_namespace
