Hi again,

So, next issue.  My default "RcppSkeleton" package now 
installs fine and library(RcppSkeleton) works fine.

However, when I run the one function in the package, 
rcpp_hello_world(), I get this problem:

 > rcpp_hello_world()

Error in .Call("rcpp_hello_world", PACKAGE = 
"hello_world_Rcpp") :
   C symbol name "rcpp_hello_world" not in DLL for package 

Any suggestions?  I looked at the PDF FAQ on CRAN here:


...but no luck.

Thanks again, I know everyone is busy!
