Precisely my point, Brian. The usage and meaning of '...' are
almost impossible to find in the help system. Could there be a
help page for it ? Questions about '...' are reasonably frequently
asked on this list.
While we're at it, what could be done so that help.search("logistic")
returns a reference to glm() and help.search("regression") returns
references to both lm() and glm() ?
