R inline compilation of C code fails on Windows

Within the Windows XP Pro RGui, can't compile inline C code. Get error: 'sh' is not recognized as an internal or external command

Clearly there is a configuration error, but can't find a way to resolve it either in R documentation or via googling. Must be a sim开发者_运维知识库ple solution!

The same R code works fine on linux: the inline C compiles and runs correctly.

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