[R] na.exclude equivalent

[David Kane <David Kane]

Is there an R equivalent to the na.action "na.exclude" in S+ for use in lm()?
My basic problem is that when using resid() to grab the residuals from an lm
object, I would like place holders for the missing values caused by NA's among
the input variables. na.omit, of course, removes those observations entirely,
so I don't know (without going to the trouble of matching up row.names) which
residuals line up with which input observations.

Thanks,

Dave Kane
