I can't seem to get this to run locally on my mac

This is my error message at the end:

covariate_size_effects_error <- system(paste0("Rscript covariate-size-effects.r ", filename,'-stanfit.Rdata'),intern=FALSE) Loading required package: magrittr This is bayesplot version 1.7.1

• Online documentation and vignettes at mc-stan.org/bayesplot
• bayesplot theme set to bayesplot::theme_default()
• Does not affect other ggplot2 plots
• See ?bayesplot_theme_set for details on theme setting

---

Note: As of version 1.0.0, cowplot does not change the default ggplot2 theme anymore. To recover the previous behavior, execute: theme_set(theme_cowplot())

Attaching package: ‘cowplot’

The following object is masked from ‘package:ggpubr’:

get_legend

Hi @Kumereng, on Mac stan has issues. Please see in here https://github.com/stan-dev/rstan/wiki/Catalina-problems Best option would be to use our docker or use envionmnet.yml and create the enviornment using conda

Another option is to run in a linux virtual machine, though no idea how efficient that is.
