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?

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].

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So the online documentation source is outdated.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.

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

Dear Sir,

Many thanks for your reply. May I ask,was it replaced by another similar
function? It seems interesting enough to have a function like that.

Dear Ashim,
No.
I guess it didn't seem that useful to us. You can simply modify commands in a programming editor.

Best,
 John

Since R is open source, the source code for packages is stored on CRAN mirrors. A little navigation gets us to 

https://cloud.r-project.org/src/contrib/Archive/car/

Loading car_1.2-16.tar.gz, the last version before car_2.0 gives the code for Ask():

# change an argument to a function interactively (J. Fox)

Ask<-function(arg, fun, ...){ 
    fun<-fun
    repeat{   
        value<-readline(paste("Enter",deparse(substitute(arg)),": "))
        if (value == "") break()
        eval(parse(text=paste("fun(",deparse(substitute(arg)),"=",value,",...)")))
        }
    }

Running this code will create the function.
