I wonder what happened, for R to hide the underlying Scheme so fully,
at least at the level of the surface language (despite there are
hints).
To further foster portability, we chose to write R in ANSI

I meant that R might have implemented a Scheme engine [...] with
a surface language [...] which is purposely not Scheme, but could have
been. [...] one could dare dreaming that the Scheme engine in R be
completed, and Scheme offered as an alternate extension

You could also look at Ross Ihaka's paper that is online here:

Interesting read. Thanks for this reference!

Yes, of course. Scheme is also (often) implemented
I mainly program in Common Lisp and use R for statistical analysis.
While in R I miss the power and ease of use of Lisp, especially its many
primitives such as find, member, cond, and (perhaps a bridge too far)
loop.
Has anyone created a package that includes R analogs to a subset of Lisp
Reduce, Filter and Map are part of R 2.6.0. Try ?Reduce

As far as I understood, the original version of Ihaka/Gentleman was
written in Scheme. But even if you look at the source
