Interfaces RStan

  • Operating System: macOS Mojave Version 10.14.5
  • RStan Version: 2.18.2
  • R version 3.6.0 (2019-04-26)
  • Platform: x86_64-apple-darwin15.6.0 (64-bit)

In both RStudio and R from the Terminal, R crashes/aborts after 1 chain (sometimes, not always).

Any advice? Thanks!!

Upgrade to 2.19.2 and if the error is still there, tell us what the Stan program is.
