We were looking at conducting a pilot program with Dell to virtualize our lab environments. We are specifically looking at Dell/Citrix provisioning servers. The OS in this setup is streamed from the server on every boot. I was curious if the R Project had any licensing stipulations in this type of setup. This is in the beginning phases and we wanted to answer some questions about licensing. I've heard a lot of other universities have hit road blocks with licensing and we were hoping to get some of these questions answered early on. Thanks.

Thanks.R is licensed under the GPL (GNU Public License), so there are no functional restrictions on use, only subsequent distribution. My understanding of the scenario you are describing is that you have some number of diskless workstations, connected to a network server providing the operating system and applications to the workstations via a Citrix service upon boot of the workstations. You would just need to be sure that R is part of the virtual disk image provided to each client workstation. I don't see any issues there, so I am not sure what licensing issues that are relevant to R are being raised by the other universities. HTH, Marc Schwartz
I have this matrix in R, s1 s2 s3 s4 g1 1 0 0 0 g1 0 1 0 0 g1 0 0 1 0 g2 1 0 0 0 g2 0 1 0 0 g3 1 0 0 0 g4 0 0 1 0 g4 1 0 0 0 g4 0 1 0 0 g4 0 0 0 1 I want to split this matrix based on its rows then sum based on columns, finally I want to make this matrix: s1 s2 s3 s4 g1 1 1 1 0 g2 1 1 0 0 g3 1 0 0 0 g4 1 1 1 1 I will appreciate if you guide me.

Dear Sir/Madam it is my the first time in using R-help center. I would like to know how can I install DEA package on my R program. moreover, is there any example of using R for calculating Malmquist? and should I necessarily install DEA package for that reason? I have some problems in importing my inputs and outputs to R. I do like this x1>(copy and paste the first input column) x2>(copy and paste the second input column) y> (copy and paste the output column) then I do not know what should I do??? I want to have Malmquist components. performing bootstrap. sincerely yours Maryam ---------- Forwarded message ---------- From: <r-help-request@r-project.org> Date: Wed, Feb 15, 2012 at 5:46 PM Subject: Welcome to the "R-help" mailing list (Digest mode) To: farhadim58@gmail.com Welcome to the R-help@r-project.org mailing list!

Sorry about that -- forgot the case where you might only have a certain entry once: try this, sapply(split(GS, rownames(GS)), function(x) colSums(as.matrix(x))) or sapply(split(GS, rownames(GS)), function(x) if(is.matrix(x)) colSums(x) else x) I'm not sure if there's a way to force split to give you matrix elements back but it would be nice. Michael PS -- It's nice to cc the list on follow up questions as well so others have a chance to answer and you get a quicker reply (since there are R-helpers in most every timezone, many of whom know much more R-fu than me.)
