Expand description

setMethod("$"), .DollarNames.Class, and with setters setMethod("$<-"), for an S4 class with s4(r_data_accessors). An S4 object of the class is no list (its only slot is ptr), so a name that is not a field raises miniextendr_no_field. The methods pass x@ptr to the accessors. .DollarNames is an S3 method, which utils dispatches on the S4 class; it is registered unless the class is noexport, as an S3 class’s methods are.
