R CMD on Windows 7 Error - “R” is not recognized as an internal or external command,

Question

I\'m exploring package building on Windows 7 but have been running into trouble after reaching the Command Prompt stage. The following thread appears to be on the same topic

Answer 1

I attach my whole solution here:

1. Install Rtools which is compatible with my R version
2. Add PATH: C:\Program Files\R\R-2.15.1\bin\x64;C:\Rtools\bin;C:\Rtools\gcc-4.6.3\bin
3. In cmd, enter: R CMD INSTALL packagename

Click "enter", done.
