As described in 
<https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17242>, R base 
functions are currently inconsistent in asking interactive "yes/no" type 
questions.  One solution to this is to have a function to do it, and to 
use it consistently.

Rather than just writing such a function and possibly missing some 
desirable feature, I'd like to ask if anyone can point to an existing 
one that is perfect (or nearly perfect, and point out what changes would 
be desirable)?

Perhaps worth pointing out "yesno" as a candidate:


https://CRAN.R-project.org/package=yesno
<https://cran.r-project.org/package=yesno>

Cheers, Mike

Not really as

 i)  base R will not have dependencies outside of it

 ii) more importantly, Duncan asked for a good example of a "consistent" (as
     in: predictable) question function yet you submit one which by design
     *varies* answers to be less predictable.

Yes, there are reasons to have questions that vary randomly, but I think 
they don't apply to the situations where I want to use this.
