Path problem installing RStan in RStudio in 64-bit Windows 10


#1

I installed RStan according to the instructions on

system(‘g++ -v’)
Using built-in specs.

Sys.getenv(‘PATH’)
[1] “C:\Program Files\R\R-3.4.0\bin\x64;C:\RTools\3.4\bin;C:\RTools\3.4\mingw_32\bin;C:\RTools\3.4\bin;C:\RTools\3.4\mingw_64\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Users\WoodwardS\AppData\Local\Microsoft\WindowsApps;C:\MinGW\bin”

It looks like Rstan is looking for g++ on the E drive for some reason?

fx <- inline::cxxfunction( signature(x = “integer”, y = “numeric” ) , ’

  • return ScalarReal( INTEGER(x)[0] * REAL(y)[0] ) ;
  •                        ' )

RStan installation failure, R 3.4.2 on 64-bit Windows 10

I found the answer here

You have to edit the path in the following line. Beats me why Rtools just doesn’t install in this directory.

cat(‘Sys.setenv(BINPREF = “C:/Rtools/mingw_$(WIN)/bin/”)’,
file = file.path(Sys.getenv(“HOME”), “.Rprofile”),
sep = “\n”, append = TRUE)
