[Rcpp-devel] Question about modules
Thanks. Got it working. Looks very promising. Any progress/work-arounds for enums? I have a ton to deal with. THK On Thu, Jan 9, 2014 at 11:31 AM, Romain Francois

Hi, The module docs is probably the one in the worst shape. I think the current recommendation is to have this in one of your .R files: loadModule( "yourmodule", TRUE ) which triggers a load action for when the package is loaded. Romain Le 9 janv. 2014 ? 17:45, Tim Keitt <tkeitt at utexas.edu> a ?crit : OK. Not quite as automatic as I thought. Its now loading the class using 'loadRcppModules' in '.onLoad'. Still a little lost. I'll have to re-read the modules docs. Not sure how to use the class. The factory did not get exposed. Do I have to expose it separately eg using attributes?

Thanks. That at least compiles. (If anyone is curious, through trial-and-error it appears .factory is not a template and takes a single argument, the factory function pointer.) However I am not seeing any of my functions exported to the package. How would the factory be called from R? I sort of understood that exporting in packages was automatic. Do I have to manually create the module in R? THK On Thu, Jan 9, 2014 at 4:40 AM, Romain Francois <romain at r-enthusiasts.com

Hello, You can use .factory instead of .constructor in that case. Romain Le 9 janv. 2014 ? 03:16, Tim Keitt <tkeitt at utexas.edu> a ?crit : I did a little experiment with RCPP_MODULE trying to wrap a class from another library. The class in question has a protected default constructor and uses a non-member factory function for instantiation. In short I did not get it to work. I am assuming that if you do not include a .constuctor statement, then the class does not get wrapped in the module. Is that correct? THK -- http://www.keittlab.org/
