Hi all, The profr package provides a method for displaying its output with ggplot: ggplot.print. You don't need this ggplot2 to use profr, so ggplot2 is listed under enhances in the DESCRIPTION file. If I have just S3method(ggplot, profr) in my NAMESPACE, then I get: ** testing if installed package can be loaded Error : object 'ggplot' not found whilst loading namespace 'profr' ERROR: loading failed If I have both S3method(ggplot, profr) and importFrom(ggplot2, ggplot), then I get: * checking package dependencies ... ERROR Namespace dependency not required: ggplot2 What's the correct way of exporting an S3 method for a generic in a suggested package? Thanks, Hadley -- Assistant Professor / Dobelman Family Junior Chair Department of Statistics / Rice University http://had.co.nz/
