The quick advice to avoid many of the RStan Windows issues:

- do not install RTools in a path with spaces. If possible, install in the default location (C:/Rtools40)
- place your R package library in a path without spaces
- if you are using R 4.0, make sure to install RTools 4.0 and run

```
writeLines('PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"', con = "~/.Renviron")

```

after installation (and then restart R). This is suggested in [RTools instructions](https://cran.r-project.org/bin/windows/Rtools/#putting-rtools-on-the-path) as well.

@bgoodri compilation not working if RTools is installed in a path with spaces and brackets is an R issue. Does it make sense to report that, given that its a general R issue? And where does one report that if yes?
