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. > sessionInfo() R version 3.0.1 (2013-05-16) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8 LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=C LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] RcppArmadillo_0.3.900.0 Rcpp_0.10.3 inline_0.3.13 loaded via a namespace (and not attached): [1] tools_3.0.1 _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
