problem installing R brms package on macOS Big Sur and R 4.1

Hi,
I’m wondering if anyone has successfully installed all the required R packages for an AFNI installation on a mac machine with macOS Big Sur and R 4.1? I have been able to resolve other AFNI installation issues on macOS Big Sur documented here: https://afni.nimh.nih.gov/afni/community/board/read.php?1,165588,165588#msg-165588 but I am still struggling with the brms package. I am getting errors indicating that some of the dependencies required for brms are not being installed successfully. I was able to resolve an error for the openssl package but brms appears to also need additional packages that are failing to install: V8, rstan, shinystan, projpred.

I was unable to resolve this issue with the information from a previous post I found related to the brms package: https://afni.nimh.nih.gov/afni/community/board/read.php?1,160090,160090#msg-160090

Has anyone else encountered a similar issue?

Thank you,

Michael

Hi Michael,

brms appears to also need additional packages that are failing to install: V8, rstan, shinystan, projpred.

It is indeed frustrating to deal with various dependency issues in R package installation I also experience this kind of problems from time to time. You may try to install those packages (V8, rstan, shinystan, projpred) individually at the R prompt, and then trace back to the root of the problem. This could be tedious, but it may work.

Thanks, Gang. I have been attempting to do this but have yet to be successful. What AFNI processes rely on the brms package? E.g., is it possible to use afni_proc.py without this package?

Thank you,

Michael

Michael, only the following 4 programs would require installing brms:

RBA, MBA, TRR, PTA

OK thanks!
