I'm not sure if this is the official behavior but I would expect the na.action function applied to a lm object to return the na.action. Here is what I mean.
> x<-0:10 > y<-x+rnorm(10) Warning message: In x + rnorm(10) : longer object length is not a multiple of shorter object length > y[5]<-NA > m<-lm(y~x) > m$na.action 5 5 attr(,"class") [1] "omit" > na.action(m) NULL I would expect na.action(m) to return m$na.action. This is simple enough to fix with na.action.lm<-function(object,...)object$na.action but I would expect that this would already be included in the base. Is there a reason that it is not? I did a search through the archives but did not turn up anything relevant.
