A general description is here.
‘plot(<lm>, which = *)’ now correctly labels the contour lines for the standardized residuals for ‘which = 6’. It also takes the correct p in case of singularities (also for ‘which = 5’). (PR#17161)
‘bartlett.test()’ used residual sums of squares instead of variances, when the argument was a list of ‘lm’ objects. (Reported by Jens Ledet Jensen).
