Calling C code from R
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 http://www.murdoch-sutherland.com/Rtools/ http://www.stats.uwo.ca/faculty/murdoch/software/debuggingR/ Also, it would be great to upgrade R to 2.4.1

I am using R-2.4.0 on Windows XP. I am trying to create dll file.
My C code:
/* useC1.c */
void useC(int *i) {
i[6] = 100;
}
I have tried to create useC1.dll.
C:\R-2.4.0\bin>R CMD SHLIB useC1.c
'perl' is not recognized as an internal or external command, operable
program or batch file.
Then I have tried:
C:\R-2.4.0\bin>Rcmd SHLIB useC1.c
'perl' is not recognized as an internal or external command, operable
