[Rcpp-devel] How do I convert my prototyped code to a package ?

[Ricardo Silva]

Hi,

following

http://dirk.eddelbuettel.com/code/rcpp/Rcpp-FAQ.pdf

and this

help("package.skeleton-methods")

I use to convert my prototype function as


functions <- cxxfunction(
+              list(
+                      ff = signature(),
+                      gg = signature( x = "integer", y = "numeric" )
+              ),
+              c( "return R_NilValue ;", "return ScalarReal(
INTEGER(x)[0] * REAL(y)[0] ) ;")
+      )
>      package.skeleton( "foobar", functions )
>> standard package.skeleton from utils
Creating directories ...
Creating DESCRIPTION ...
Error in if (!namespace) warning("From R 2.14.0 on, every package gets
a NAMESPACE.",  :
  argument is of length zero

but now I get the above error,

someone know what is wrong.
