| Your package is called "RcppSkeleton", isn't it? If so, that should be

|
| .Call("rcpp_hello_world", PACKAGE="RcppSkeleton")
+1
And that is what should have gotten filled in as rcpp_hello_world.R in
inst/skeleton/ (which gets copied) has:
rcpp_hello_world<- function(){
.Call( "rcpp_hello_world", PACKAGE = "@PKG@" )
}
and all that works here:
R> Rcpp.package.skeleton("rcppSkeletonTest", path="/tmp")

Ok?

Yep, I get the same behavior now, my R function was
reflecting a previous definition from a previous install
attempt with the hello_world name I think, it went away
after reinstalling, re-library-ing after detach() and
remove.packages() on previous attempts.
Thanks!
