[R] Installing pre-compiled R in Linux

[Michael Hannon]

I don't think kernel compatibility is a significant issue for most
applications.  I can say for certain that I update the kernels on my
linux boxes without having to reinstall R.

There *are* R packages for RHEL and friends.  Have a look at:

https://cran.r-project.org/bin/linux/redhat/README

Note that there's a bit of fiddling required, but I don't think it's
particularly complicated.

It's usually not particularly difficult to install R from source.  If
you prefer to do that, have a look at:

https://cran.r-project.org/doc/manuals/r-release/R-admin.html

Also, you don't specify your requirements, but don't overlook the
possibility of installing a virtual machine on your RHEL server.
(It's somewhat easier to get an R package for Fedora or Ubuntu than
for RHEL, for instance.)

I don't know the answer to your question about embedded systems.  I
would think R would not be a great choice for an embedded system, but
I don't know what your requirements are.
