R for commercial use

Hi,

Hi everyone,
want to use R in our company but have to complete an intern questionnaire first. Can anyone help? Thanks in advance!
Here the questions I?m not sure about:
1.      Is R a Clientsoftware / Serversoftware / Systemsoftware?

This is a strange choice. what would you answer for e.g. Excel??
It's most certainly no Server.
It's not a Client, because there is no "R-Server". But R can establish
connections to several Server Types, for example to download data. R
Packages can extend R's funcionality
What's "Systemsoftware"??

2.      Does R need a ?chellenge-response? treatment for activation?

Dunno what "challenge-response" is. But R is open-souce, no activatoin
required.

3.      Is R proxy-able?

HTTP-Proxying seems to work, google "GNU R proxy" and see
<http://cran.r-project.org/bin/windows/base/rw-FAQ.html#The-Internet-download-functions-fail_002e>

4.      Is the personalised WINDOWS-NTLM-authorization at ISA-proxy possible?

Don' know. But you can run R without any changes to a Windows system,
like registry entrys and such. Copy the folder and execute R.exe

5.      Are any exceptions for virus scanner needed? If yes, which ones?

No.

6.      Does R changes system files or folders? (e.g. system32, registry). If yes, which ones?

No.

Moritz
