-NOTE: If using R version >4.2 and RTools42 on Windows, then this package will not work with the CRAN version of rstan (see the Stan [blogpost](https://blog.mc-stan.org/2022/04/26/stan-r-4-2-on-windows/) for more information). Instead, remove your old `rstan` and `StanHeaders` and install the `rstan` version from the Stan repository rather than CRAN using the following commands:
-
-```
-remove.packages(c("rstan", "StanHeaders"))
-install.packages("rstan", repos = c("https://mc-stan.org/r-packages/", 
-                                    getOption("repos")))
-```

-If you're still experiencing problems please raise an issue on github.
