So i use anaconda for all this, the problem is when i try to do:

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

It seems that R is requiring administrator privileges to be accessed. However you're launching your environment (IDE/Anaconda), right click and 'Run as administrator'.

  • No, if a program requires administrator access, and the caller isn't elevated, `CreateProcessW` fails with `ERROR_ELEVATION_REQUIRED` (740). – Eryk Sun Apr 12 '19 at 10:20
  • Oh okay. My response was based on the WinError 5, which is also in line with the response here: https://stackoverflow.com/a/27801762/3443106 . – Maher Said Apr 13 '19 at 00:22
  • That's almost always not the case. Standard users have read and execute access to files installed in normal places. If you read the comments on the question itself, you'll see it was resolved by specifying the full path of the executable instead of its directory, i.e. the poster was trying to execute a directory via `CreateProcessW`. The 28 upvotes on that answer are a common problem with Stack Overflow. An upvote doesn't mean the votes are informed by reading documentation, debugging, and experiments, or that the voters have even a passing familiarity with the underlying API calls. – Eryk Sun Apr 13 '19 at 03:20
