R version

[crancran2]

I'm unable to install this package and get this error message: "package ‘mixedup’ is not available for this version of R." package may need updates.

Maybe you need to update R, because the recommended installing method just worked for me:

remotes::install_github('m-clark/mixedup')

I have R version 4.0.3

It depends on at least R 3.6. But let me know if you still have issues.

remotes::install_github('m-clark/mixedup')

# if you don't already have rstanarm and/or brms

withr::with_envvar(c(R_REMOTES_NO_ERRORS_FROM_WARNINGS = "true"), 
  remotes::install_github('m-clark/mixedup')
)

Going ahead and closing until something comes up.
