[R] restore NAs in residuals

[Gabor Grothendieck]

Try this:

> resid(lm(tt~year, na.action = na.exclude))
         1          2          3          4          5          6          7
 0.7114894  1.2231383  0.1447872 -1.8035638 -0.8519149 -0.5302660         NA
         8          9         10
        NA         NA  1.1063298
