[Rd] Generic Function for dffits?

[Viechtbauer Wolfgang (STAT)]

Dear All,

help(influence.measures) shows that there are generic functions for dfbetas(), covratio(), cooks.distance(), hatvalues(), and a few others, but apparently not for dffits(). Wouldn't it be more consistent to have a generic function for this in stats as well?

Best,
