A general description is here.
new generic ‘chooseOpsMethod()’ provides a mechanism for objects to resolve cases where two suitable methods are found for an Ops Group Generic. This supports experimenting with alternative object systems. Based on contributions by Tomasz Kalinowski in PR#18484.
‘inherits(x, what)’ now accepts values other than a simple character vector for argument ‘what’. A new generic, ‘nameOfClass()’, is called to resolve the class name from ‘what’. This supports experimenting with alternative object systems. Based on contributions by Tomasz Kalinowski in PR#18485.
‘anova.glm()’ prints test statistics and p-values by default, using either a Chisq test or an F test, depending on whether the dispersion is fixed or free. Test statistics can be suppressed with ‘test=FALSE’.
