问题 how do I document the use of member functions of a reference class? if I write a Rd file with a \usage block, how do I avoid the WARNING Functions/methods with usage in documentation object 'XmlDoc' but not in code: $ new I'd expect the \usage block to allow me write things like: obj <- ClassName$new(par1, par2, ...) obj$method1(oth1, ...) and then I'd document the parameters in the \arguments block. If I do this, R CMD check complains with Assignments in \usage in documentation object
