For commands like max the option na.rm is set by default to FALSE. I understand why this is a good idea in general, but I\'d like to t
It is not possible to change na.rm to TRUE globally. (See Hong Ooi's comment under the question.)
EDIT:
Unfortunately, the answer you don't want is the only one that works generally. There's no global option for this like there is for na.action, which only affects modeling functions like lm, glm, etc (and even there, it isn't guaranteed to work in all cases). – Hong Ooi Jul 2 '13 at 6:23
