under "Details" (version 2015-11-29 r69717; not quite cutting-edge,
but nothing has changed in src/library/stats/man/family.Rd in 5 months
[sorry for using the Github mirror, but I prefer the interface ...
<https://github.com/wch/r-source/blob/trunk/src/library/stats/man/family.Rd>])
it says:
valid.mu: logical function. Returns ‘TRUE’ if a mean vector ‘mu’ is
within the domain of ‘variance’.
valid.eta: logical function. Returns ‘TRUE’ if a linear predictor
‘eta’ is within the domain of ‘linkinv’.
However, the real names of these elements are "validmu" and "valideta"
(no dots); try names(poisson()) or names(binomial()) and see ...
Can someone on R-core fix this and save me the trouble of filing a
bug report ... ?
Or have I misunderstood something?
cheers
Ben Bolker
