[R] getData.lme error

[Remko Duursma]

hi list,

i am making some diagnostic plots using plot.lme(),
my lme model was fit with the option na.action='na.exclude'.

On the following (or similar) commands:

plot(flu.trees.42.w25.10.2,  resid(., type="p") ~ fitted(.)|species, abline=0)

R returns an error message: 
Error in getData.lme(object) : couldn't find function "naAct"

It turns out that the function getData.lme does:

naAct <- eval(mCall$na.action)
    if (!is.null(naAct)) {
        data <- naAct(data)
    }

however, the funcion na.exclude is not properly assigned to naAct
in this way.

Has anyone encountered this before?
What to do?

(i can, ofcourse, refit my model with excluding the NAs myself - but thats not so elegant!)

Thanks,

Remko Duursma
