A new function in my heplots package wants to use a non-exported utility function in the car package, df.terms, but this depends on other non-exported functions. From the Writing R extensions manual, I thought I could do this via (in my NAMESPACE)
importFrom(car, car:::df.terms, car:::df.terms.default, car:::is.aliased) but I get: ** preparing package for lazy loading Error : objects 'car:::df.terms', 'car:::df.terms.default', 'car:::is.aliased' are not exported by 'namespace:car' ERROR: lazy loading failed for package 'heplots' \S 1.6.1 of the manual says regarding importFrom(): Using |foo:::f| instead of |foo::f| allows access to unexported objects. This is generally not recommended, as the semantics of unexported objects may be changed by the package author in routine maintenance. Questions: 1. Why doesn't this work? 2. Is my only alternative to copy these functions to my package, also unexported? thx, -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept. & Chair, Quantitative Methods York University Voice: 416 736-2100 x66249 Fax: 416 736-5814 4700 Keele Street Web: http://www.datavis.ca Toronto, ONT M3J 1P3 CANADA [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
