| 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")
Creating directories ...
Creating DESCRIPTION ...
Creating NAMESPACE ...
Creating Read-and-delete-me ...
Saving functions and data ...
Making help files ...
Done.
Further steps are described in '/tmp/rcppSkeletonTest/Read-and-delete-me'.

[1] "foo" "bar"

[1] 0 1

R> rcppSkeletonTest::rcpp_hello_world()
[[1]]

Ok?
