Cannot run BEST functions using Apple MacBook computers with an M1 chip

[jlwoodard]

I have had several reports of students not being able to run functions in the BEST library on Apple computers with an M1 chip. I'm not sure if the problem lies within BEST of any of its dependencies or if there might be a workaround.

I can't help much with that without at least an error message!

Make sure that JAGS is installed correctly. JAGS does not appear in the Applications lists on Macs; to check that it is installed properly and to see the version, open the Terminal and type jags.

Also check that the R package rjags is working properly. In R, do library(rjags): you should get a message saying "Linked to JAGS 4.3.0". I know some people using Windows have an issue with version 4-11 of rjags not being able to find JAGS, but that should not affect Macs.

If R, JAGS and rjags are all working, BEST should be fine. If not, I'd need more info: at least the error message and the output from sessionInfo().
