This blog is updated daily.
A general description is here.
‘glm(.., wtol = <positive>)’ treats very small weights as zeros now, similarly to ‘lm()’ via ‘glm.control()’; correct AIC and logLik() for this case, fixing PR#16008, thanks to Bill Dunlap and Mauricio Vargas.
‘summary(<free1way>)’ renames p-values to ‘Pr(..)’ and
thus ‘printCoefmat’ recognises them.
‘ksmooth(x,y, x.points=NULL)’ now returns an empty (x,y) pair instead of crashing R, fixing PR#19153.
