[FORGED] Ask function missing in package car

Tue, Jun 21, 2016 7:15 PM

According to the NEWS file for the package:

  https://cran.r-project.org/web/packages/car/NEWS

the Ask() function was removed in car version 2.0-0, which was released on 2010-07-26. So it has been gone for about 6 years.

The version of car that is used in the documentation that you are using is 1.2-16, which is from 2009-10-11.

So the online documentation source is outdated.

I see that the Ask() function is listed in the first edition of John's book, which I have on my shelf, but I don't have the second edition to know if that had been updated. A review of the index for the second edition on Amazon.com would suggest that it was removed for the second edition.

Regards,

Marc Schwartz

I am reading the book An R and S plus companion to Applied Regression and I
found this function there.

Googling gave me the link [1].

Error: could not find function "Ask"

What can I do to correct this?

What led you to believe that such a function exists (in the "car" package
or anywhere else for that matter)?  And what exactly do you want it to do
for you?

cheers,
