[Rd] Can we generate exe file using R? What is the maximum file size valid?

[Stavros Macrakis]

There are two distinct and orthogonal questions here:

1) Is it possible to package an R program/system in such a way that it
can be distributed as a single executable file (including the R
system, any necessary loaded packages, plus the application program)
and run without an installation of R (which sets up library
directories etc.)?

2) Is it possible to compile R to bytecodes or machine language?

The answers to these questions are independent.  It is perfectly
possible to have an interpreted system which is distributed as a
single executable file (using e.g. unexec to save the fully-loaded
state).  It is also perfectly possible to have a compiled system which
requires configuration of library directories etc.

I believe the original question on this thread was about (1), but I am
not certain.  It also appears that the answer to (1) is 'no', but I am
not certain about that either.  I wouldn't think that it would be
impossible to add 'unexec' to R, but I don't know R's internals.
