That would be because your IT questionnaire requires telepathy to understand
what the writer wanted to know.
My take on these, in case it helps:
1. Is R a Clientsoftware / Serversoftware / Systemsoftware?
R can run both on a client or on a server.
However, it is normally installed on a client machine in the same way as Word,
Excel, Gimp etc. If you intend to install it on a desktop I suggest the answer
'client'
2. Does R need a "chellenge-response" treatment for activation?
No
3. Is R proxy-able?
R can access the internet through a proxy. Usually installing usint the
Internet2 option lets R work through Windows' existing proxy setup.
4. Is the personalised WINDOWS-NTLM-authorization at ISA-proxy possible?
I have no idea why any sensible IT staff would expect an end user to be able to
answer this question. I deduce your IT staff are not sensible. Further, this
refers to a LAN security protocol that authenticates client-server interactions
(badly, I assume, as even microsoft no longer recommend it).
I suggest you answer 'N/A' because that authentication should be handled by
client-server networking protocols and not by R
5. Are any exceptions for virus scanner needed? If yes, which ones?
Not usually; R does not trigger antivirus alerts unless the antivirus software
is making mistakes. That happened once to my knowledge.
6. Does R changes system files or folders? (e.g. system32, registry). If yes,
which ones?
R's installation process adds the R version to the registry and associates
.Rdata files with R via the usual registry mechanism. You can tell it not to do
that. Further, if it fails to do so for permission reasons R will still run
normally.
I pefer to get our admin staff to install R as administrators to get the
registry properly updated, and I also ask them to grant write permission to the
R subdirectory in the program files directory so that R can install contributed
packages there. But that is not essential; R can install packages in user space
instead if permission is not granted for program files space.
Of course if a user uses R to read and write from the system areas, then of
course it can change files there; byt that is equally true of word, excel etc.
