Dear R users,

I want to call C function from R. I follow the following instruction using the example of foo.c

I save the foo.c in my current directory. Is that right? After I enter the command R CMD SHLIB foo.c, I get the following message

Error: unexpected symbol in "R cmd"

Any suggestion is appreciated.
