Pretty good question Gabor. I can execute R once it is installed (if
someone with rights installs it before) but not the installer. I can
download the installer (with some pain). I know that some installers are
actually compressed files in disguise, but I think this is not the case
with R, right?
I will study the exact nature of the restriction, and get back to you.
Nevertheless, having a installer and a "portable" version is something
pretty common (R Studio, Notepad++ and 7Zip pop to my mind now) and pretty
helpful to deal with security restrictions, so I thought R had one,
somewhere.
I don't know what's involved in putting together such a thing, but my
guess is that official R sources will not do so. Generally speaking, R
doesn't support efforts to circumvent security safeguards.
When I was a member of R Core, we used to get enough trouble from false
positive warnings from virus checkers. If R Core started actively
trying to support system abuse, it would cause far more trouble for them.
Of course, since R is open source, there's nothing to stop some third
party from putting together a way to run R despite security policies
that forbid it. And nothing to stop them from inserting their own
malicious code into the .zip file.

Can you clarify what the nature of the security restriction is?
If you can't run the R installer then how it is that you could run R?
That would still involve running an external exe even if it came
in a zip file.
Could it be that the restriction is not on running exe files but on
downloading them?
If that is it then there are obvious workarounds (rename it not
to have an exe externsion or zip it using another machine,
upload to the cloud and download onto the restricted machine)
but it might be safer to just ask the powers that be to download it
for you. You probably don't need a new version of R more than
once a year.

What is wrong with you guys? I asked for a zip, like R Studio has for
example. Totally clear.
I cant execute exes. But I can unzip files.
Thanks Gabor, I had that in mind, but can't execute the exe due to
security
restrictions.
Geez, really, treating people who ask questions this way just makes you
don't want to ask a single one.

I believe that the ordinary Windows installer for R can produce a
portable result by choosing the appropriate configuration options from
the
offered screens when you run the installer Be sure to enter the desired
path in the Select Destination Location screen, choose Yes on the
Startup options screen and ensure that all boxes are unchecked on the
Select additional tasks screen.

I read a message from 2009 or 2010 where it mentioned the availability
of R
for Windows in a zip file, no installation required. It would be very
useful for me. Is this still available somewhere?
Thanks
