Error in compileCode

I am teaching Stan and many of my students are getting the following error when following the RStan Getting Started guide:

remove.packages("rstan")
if (file.exists(".RData")) file.remove(".RData")
# Close all RStudio sessions 

# Open RStudio
# To install rstan, run the following code
install.packages("rstan", repos = c('https://stan-dev.r-universe.dev', getOption("repos")))

# Examine if rstan is working (there is no warning)
example(stan_model, package = "rstan", run.dontrun = TRUE)


Error in compileCode(f, code, language = language, verbose = verbose) :

This is happening with fresh installations of R 4.5.0 (with RTools 45), or with 4.4.3 (with RTools 44), or with R 4.3.0 (with RTools 43) on Windows OS.

Some more information that might be relevant:

  1. At least for some I can confirm that their R library is not installed on some cloud drive.
  2. This didn’t happen last year (🤷‍♂️)

My students and I would be grateful for any help provided!

Sorry for these issues! I’ve pushed an update which should solve things.

Can you try the steps again to remove and install rstan?

If you still run into errors with the example model, can you update your Makevars.win file to suppress compilation warnings so that the result will show the error:

if (!dir.exists("~/.R")) {
  dir.create("~/.R")
}

cat("CPPFLAGS += -w -Wno-misleading-indendation", file = "~/.R/Makevars.win",
    append = TRUE)

EDIT: binaries updated on r-universe

Thanks @andrjohns - that seems to have done it!

(My students thank you as well 👍)
