Hello,

Thanks for your helpful reply.

++ Using Mac OS 10.7.5 afni version AFNI_2011_12_21_1014

++ Checked the system, all is fine
$ afni_system_check.py -check_all

++Did the following:

install.packages("snow",dependencies=TRUE)
install.packages("nlme",dependencies=TRUE)
install.packages("contrast",dependencies=TRUE)
install.packages("fastICA",dependencies=TRUE)
install.packages("afex",dependencies=TRUE)
install.packages("phia",dependencies=TRUE)

However, R is still having warning messages regarding package 'car'
Error: package or namespace load failed for 'car'

When running my 3dMVM script, now model test failed for a few possible reasons, one being to make sure that R packages afex and phia have been installed. In R under Package Manager, afex and phia are not loaded and even clicking they wont load.

Using R version for snow leopard 3.2.1 GUI 1.66

Presume I need to get the latest version of R for these packages in order to run 3dMVM, but I assume this means I have to update my Mac OS system as well?
