# File lib/R_interface/ruby_callback.rb, line 67 def callback(*args) # converts every arg into a R::Object (Ruby object that wraps an R Interop) args.map! { |arg| R::Object.build(arg) } # calls the callback method and convert the result back to an R object # method parse_arg was developed to parse the arguments to an R function # but in a callback the return value needs to be converted. In this case # the name parse_arg is misleading R::Support.parse_arg(@object.call(*args)) end
