If you don't mind multi-gig docker containers, this can be helpful:

It doesn't work with 64 bit versions of R as far as I could tell, but 32
bit did install and start correctly in a few clicks when I tried last year.
Thanks! I'm hoping if I can get this all working locally I can put
everything into a docker container for other folks. At this point I have R
up and running and it can install binary packages, but there are some
terrible terrible Cygwin/Rtools errors I can't figure out. In particular
this warning / message seems worrisome
Cygwin WARNING:
Couldn't compute FAST_CWD pointer. This typically occurs if you're using
an older Cygwin version on a newer Windows. Please update to the latest
available Cygwin version from https://cygwin.com/. If the problem
persists,
please see https://cygwin.com/problems.html
If anyone has interest I can post a script for setting up the wine instance
as far as I can get atm.
Did you have any update on this? If there is a problem with MinGW-w64
version, you can (just for experimentation) try UCRT demo build, which
uses a newer version of MinGW-w64 than RTools 4:

Are you sure you want to try to run R etc. under Wine?
Do I want to? No :-). But we (Stan) want to use flto and are seeing errors
on windows I want to be able to debug locally.
Please note Brian Ripley has added/improved support for cross-compiling
on Linux for Windows, so that it can be used for diagnosing LTO warnings
(see NEWS in R-devel and src/gnuwin32/README.compilation). The
cross-compilers and needed cross-compiled libraries for R itself are
part of at least some Linux distributions (he tested on Fedora).
- If you have Windows running, either directly or in a VM, you can run R
there.
Sadly I don't have access to a windows machine. If I can't figure this out
then I'll probably just get a windows aws instance. But it would be nice
for people to have a wine setup they could test locally on.
Microsoft is giving for free time-limited VMs primarily for testing
Edge/MSIE, you can run them in e.g. in Virtualbox. As instructed in the
VM, take snapshots often.
- If you have Windows and want to run R under some other OS, then set up a
VM
e.g., Linux Mint, for that. I sometimes test R for Windows in a
VirtualBox VM
for Win10, but generally run in Linux Mint. I've also run R in some Linux
VMs
to test for specific dependencies in some distros.
I rather doubt R will run very well in Linux under Wine. My experience
with Wine
is that a few apps (e.g. Irfanview) run well, but many give lots of
trouble.
Yes I'm 80/20 on whether compilation with Rtools will totally work on wine.
But if I can get this all setup and put it into a docker file I think it
will be useful for other people as well so it's worth spending a bit of
time on.
Being able to test R on Wine may be useful, if you figure it out, I
would be interested to learn more. It is easier to obtain, may be easier
to automate, and some low-level bugs may be easier to diagnose. Of
course, for the price of sometimes seeing errors not present on real
Windows.

Does anyone know of a setup guide for getting R and Rtools 4.0 up and
running on Wine with the Windows Server 2008 R2 VM? Do other maintainers
with more knowhow think that would be useful for debugging purposes?
I've been trying to test out some flto gcc things for windows by
setting up
a local wine VM on my ubuntu box. Wine has an option for Windows Server
2008 R2 (which I believe is the windows session CRAN uses?) If anyone
has
done this before and knows of a guide somewhere that would be very
helpful!
