I have a student who can’t install the latest version of Rstan because of some indexing problem with the mc-stan https site. I’ve done all I can and can’t seem to help her. We are trying
install.packages("rstan", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))
and geting “unable to index repository” errors.
But we need Rstan > 2.21.2 b/c we can’t seem to add controls to the Stan function without it. It’s worked to download with this code for all the rest of my students.
I’m a statistician, not a computer scientist, and I’m having trouble figuring out how to simply download the source file.
Any thoughts?
