R can't find function pure.error.anova

Question

I am trying to create an ANOVA table with pure errors and lack-of-fit errors , but R gives me the following message when I try to use the function pure.error.anova :

Error: could not find function pure.error.anova

Why isn't this function being found?

Answer 1

That's because the function is now deprecated. Use pureErrorAnova instead.

library(alr3)
?pureErrorAnova # to see the help file.
