[R] glm.fit when family argument is not a "family" object

[Mathew McLean]

The documentation for glm/glm.fit indicates that the family argument "can
be a character string naming a family function, a family function or the
result of a call to a family function".

glm.fit(1, 1, family = "gaussian")

## Error: $ operator is invalid for atomic vectors

glm.fit(1, 1, family = gaussian)

​## Error: object of type 'closure' is not subsettable

glm.fit(1, 1, family = gaussian())  # works​, results omitted
