[R] Calling C code from R

[Vladimir Eremeev]

You need to install perl and MinGW, at least.
If you have them installed, then you need to properly set PATH environment
variable and, probably, restart your command line session.

See chapter 5 of the manual "Writing R extensions" (installed in
R_HOME/doc/manual)
and these two links

Also, it would be great to upgrade R to 2.4.1
