Fatal Error for Rcpp in Rstudio on windows machine

I have R Studio(and R of course) and am aiming to use the Rcpp package.I am using a windows machine.

  1. I installed R tools. The folder lies in C:\Rtool

  2. I changed my PATH in control panel->system->advanced system settings->environment variables and added 2 new PATH s C:\Rtools\mingw_32\i686-w64-mingw32\bin and C:\Rtools\bin with each of those at the top of the list of PATHs

  3. I restarted my computer

  4. Started a new C++ script in rstudio

  5. Loaded the rcpp package with library()

  6. Ran the pre-existing code(timesTwo) by hitting the Source button in horizontal bar.

And I get an error message

The application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information

Also a pop-up alert comes out stating

R Session Aborted. R encountered a fatal error. The session was terminated.

By running library(rcpp) and sessionInfo() I get version information

R version 3.3.1 (2016-06-21)
Platform: i386-w64-mingw32/i386 (32-bit)

attached base packages:
[1] stats graphics grDevices utils datasets methods base

other attached packages:
[1] Rcpp_0.12.6

loaded via a namespace (and not attached):
[1] tools_3.3.1

Can anyone tell me what is wrong and how can I fix it?

Answer Source

Two issues:

  1. You are using 32 bit version of R on a 64-bit OS
  2. The path setup for Rtools is incorrect.

The path should have:
