[R] [FORGED] Ask function missing in package car

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So the online documentation source is outdated.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
