The ‘formula’ method of ‘aggregate()’ now matches the generic in naming its first argument ‘x’ (resolving PR#18299 by Thomas Soeiro).
This means that calling ‘aggregate()’ with a formula as a named first argument requires name ‘formula’ in earlier versions of R and name ‘x’ now, so portable code should not name the argument (code in many packages did).
The ‘formula’ method of ‘aggregate’ now matches the generic in its
first argument, fixing PR#18299 by Thomas Soeiro.
‘setAs()’ finds the correct class for name ‘to’ when multiple packages define a class with that name. Thanks to Gabor Csardi for the report.
Fix detaching a package when two classes of the same name are present in method signatures for the same generic. Thanks to Gabor Csardi for the report.
The ‘data.frame’ method of ‘rbind()’ now warns when binding not-wholly-recycling vectors, by analogy to the default method (for matrices).
