[FORGED] Ask function missing in package car

Dear Ashim and Marc,

Sorry to chime in late. As Marc suggests, the Ask() function went the way
of the dodo before the second edition of the book (coauthored with Sandy
Weisberg, and retitled "An R Companion to Applied Regression") was
published.

Best,
 John

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So the online documentation source is outdated.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

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,
