R help - Nov 2012 - calling c function from R

Hello

I want to call C function from R. I follow the instruction below using the
example of foo.c
http://www.stat.umn.edu/~charlie/rc/

I saved the foo.c in my work directory. Then I entered the command

R CMD SHLIB foo.c , I got the following message



Error: unexpected symbol in "R CMD"


How did it go wrong? Thanks!

Regards

Not how but why?
The message is given by R when  the syntax is wrong.

You didn't do what you were supposed to do according to the instructions.
The command

R CMD SHLIB foo.c 

should be executed outside of R.
