R inline compilation of C code does not work on Windows

Question

It is not possible to compile embedded C code inside Windows XP Pro RGui. Get an error:   'sh' is not recognized as an internal or external command

It is clear that there is a configuration error, but cannot find a way to solve it either in the R documentation or through googling. Should be a simple solution!

The same R code works fine in linux: embedded C compiles and works correctly.

Answer 1

You need a collection of RTools, as described in detail in Appendix D of the R Installation and Administration Guide .
