[R] 2nd R Console
Hi, I was reading a thread: [R] 2nd R console and had a similar question regarding having more than one R console open at a time. However, my question differs from that of the thread: Is it possible, or is there a wrapper that will allow one, to open an arbitrary number of R consoles which access the same R session (all objects in that session, etc.). This would be R on linux accessed through a shell - kind of like using GNU screen multi-user such that people could work collaboratively on a given session. The problem with screen is that all commands are interleaved in the same terminal, which is confusing and does not allow access to the command prompt at the same time, rather it would be sequential. I know there will be why questions but it is useful in an academic environment. Basically we have a memory machine for large genomic analysis - and we could set that up as an Rserver, but this placing R into a multi-user engine is better suited for our immediate needs. Does anybody have thoughts on this?

Does anybody have thoughts on this? You could have a look at XMX (X-protocol Multiplexer). This is now rather old, and I think it has not been further developed for many years. http://www.cs.brown.edu/software/xmx/README.patch7 Basically, you would start XMX from one machine (A) networked to others (B,C,...), all running X-windows. in the startup, you designate which machines are to share the session, and what rights they will have. On machine A, and all designated machines B, C, ... , appears a window. This in fact acts like a screen emulator, with its own X session inside it. The A user then starts up a program (say R) in this window, and what A sees is mirrored on the other machines. If A has granted input privileges to the other machines, then users of B, C, ... can do things themselves, and the effects of their actions are mirrored to all the other machines. Thus, for instance, it would be possible for different users to take turns at entering commands into the R session, and so on, from their own machines. This is a much better way of arranging things, than having all the people queue up to take turns at sitting in the one and only chair! It is certainly useful in a classroom situation, and even in a one-to-one tutorial. For instance, I've used it in the past to teach programming and system management, sitting more or less beside the other person but at different machines. We would both, for instance, be editing the same program file, and either could initiate a program run with the current file. (Of course, what's technically called a race condition can develop here ... ). I've even envisaged the scenario where two people, one in England and one in the US, could simultaneously be editing a joint paper (you'd also need an independent communication channel as well, but that's no problem using a chat program). The one constraint with XMX (at least in the past, I'm not sure to what extent it may have been relaxed) which can limit its use is that it depends on fairly close compatibility between the X resources of all the different machines. It's best of they're identical (same screen resolution e.g. 1024x768, same colour depths on all screens, ... ). Otherwise it's liable to not establish the necessary connections, and only some machines can join in. However, in a computing lab environment, it may well be that all machines are compatible. Suck it and see! Hoping this is useful, Ted.

Re: [R] 2nd R console?
I never tried opening more than one instance of Rgui, but when I wanted to run two jobs at the same time on one Win XP PC, I would run one in Rgui and one in Rterm and I have never had a problem with that setup. As above, when I close my R session, I always say no to the save question.

Never used that, but go to your bin folder and see if you see both Rgui.exeand Rterm.exe. If so, you can definitely use that method.
