@bgoodri - Thank you for all of your help. I have run into the same issues, and I have tried the fixes proposed in this thread as well as the suggested steps in a related thread (Not able to run Eight Schools example on rstan 2.21.1 & StanHeaders 2.21.0-5) with no luck.
I tried running:
install.packages(
"https://win-builder.r-project.org/8bPDZPDG0522/rstan_2.21.2.zip",
repos = NULL, type = "win.binary")
But got the error message:
Warning in install.packages :
cannot open URL 'https://win-builder.r-project.org/8bPDZPDG0522/rstan_2.21.2.zip': HTTP status was '404 Not Found'
Error in download.file(p, destfile, method, mode = "wb", ...) :
cannot open URL 'https://win-builder.r-project.org/8bPDZPDG0522/rstan_2.21.2.zip'
Did the ZIP file get removed?
