[Rcpp-devel] round function not found?

[Simon Zehnder]

Hideyoshi,

following http://dirk.eddelbuettel.com/blog/2012/10/01/, this should work though. 

Also using the inline package I get the correct result:

src <- 'return Rcpp::wrap(round(3.2));’
cfunc <- cxxfunction(body = src, plugin = "Rcpp”)

cfunc()
[1] 3

Best

Simon
