r = pyper.R(RCMD="D:/Apps/Anaconda/envs/rstudio/lib/R",use_pandas='True')

but then the error apear :

  • `CreateProcessW` fails with `ERROR_ACCESS_DENIED` (5) if the executable file doesn't grant execute access (rare in Windows, especially on personal systems) or if you try to execute a directory. My guess would be that "D:/Apps/Anaconda/envs/rstudio/lib/R" is a directory. – Eryk Sun Apr 12 '19 at 10:18
  • Ok this really works, thanks! and the executable is in "\Scripts\R.exe" according to this : https://github.com/ContinuumIO/anaconda-issues/issues/777 – ALDY NOAH Apr 13 '19 at 06:14
