Inquiry about the behaviour of subsetting and names in matrices
...e usage of NAs by design. i.e. when you choose an unknown object from a set of objects the result is an object, but nobody knows which - hence NA. Is it really accepted now that such a decision was a mistake and lead to bugs in user code?
Kind regards,

In my opinion adding these features would improve the consistency of R but would add more sources of bugs in an already unsafe language.

Documentation bug?
...hy-is-predict-not-ignoring-my-offset-from-a-poisson-model-in-r-no-matter-how-i
Digging deeper in R history, it seems that this note was also found in "glm {stats}" in R 1.0.0 but was removed in R 1.4.1. Maybe somebody forgot to remove it in "lm {stats}" too.

Poor family objects error messages
...mial family the
links logit, probit, cauchit, (corresponding to logistic, normal and Cauchy CDFs respectively) log and
cloglog (complementary log-log); [...] If the link function is given as a character string, all families accept all link functions.
What do you think of that ?

Bug or feature?
...ta, environment(Terms))
The same modification would have to be done two lines after:
offset <- offset + eval(object$call$offset, newdata, environment(Terms))
However, fixing this inconsistency could break code that rely on the old behavior.
What do you think of that?

Inquiry about the behaviour of subsetting and names in matrices
Hello,
I have stumbled upon a few cases where the behaviour of naming and subsetting in matrices seems unintuitive.
All those look related so wanted to put everything in one message.
1. Why row/col selection by names with NAs is not allowed?
x <- setNames(1:10, letters[1:10])
X <- matrix(x, nrow=2, dimnames = list(letters[1:2], LETTERS[1:5]))
x[c(1, NA, 3)] # vector: works
