``lm_robust`` object does not provide some accessors

[jlgraves-ubc]

Hi there,

I'm trying to do some work with this package, particularly for people who mainly use STATA and the lm_robust function is wonderful. However, the object it returns it doesn't seem to provide some of the standard accessor functions that lm does, which means it breaks other packages that rely on those functions. In particular, I have noticed that:

• deviance and residuals both return NULL
• coefficients works fine

There might be some other ones, but these were the ones I was working with. Am I mistaken or are these not associated with the object?

Yes, I think so! Thanks for tagging those.
