Pleasure! It was a very valid question qestion.

This list may actually be the best place to start assembling 'best practices'
for coping with several installed versions, in one wants to, on Debian /
Ubuntu.  I guess some people just install into /usr/local/lib/R-$version and
then set the path on the fly, but I am not sure how to best deal with a
common (or separate ?)  R_LIB paths -- I personally don't need multiple
versions at the same time :-) so I don't spend much time there.

But it may make sense to, say, start taking some HOWTO notes on
wiki.r-project.org or some other place. 

As it might for, say. ways to combine Debian CRAN packages with CRAN packages
etc.  All of this is somewhat underdocumented....

Cheers, Dirk

| /usr/local/ is yours, /usr is for the packaging system.  That is a strict
| boundary that is never crossed.
| Under /usr, the current package lives in one place and does therefore not

| feasible. Emacs does it, and many other apps allow to have multiple versions
| installed. I once engineered the same rewrite to have several Octave versions
| installed.  It is possible --- but it also requires a more-or-less complete
| rewrite of the package infrastructire, and then tests, of all associated
| scripts and files. I will have to leave that for other volunteers as I don;t
| have the time to drive that change.
| So in the short run, go with your own builds in /usr/local if you need
| several versions at the same time.
| | Yes all the Bioconductor development version is on R 2.9. There are many
| | thousands of bioconductor users who stay on the development version of
| | R . This is where I prefer to be, this was easy with windows,  I could
| | install as many versions of R as I like 2.7, 2.8.1, 2.9 .... The
| | bioconductor libraries are smart enough to know the R version you are
| | running  and use the correct repositories for their libraries. But that
| | is the dark ages I don't want to return to!
| | 
| | The option of a virtual install seems unnecessary surely ? I am familiar
| | with that but I don't want to chop up my memory of each instance as I
| | need it all for some jobs.
| | 
| | As you can tell this is my first foray into this topic and I certainly
| | don't to put any more demands on you time. I guess I did not realise it
| | was either one or the other 2.8.1 or 2.9.0 ? I did not anticipate that.
| | Is the reason just trivial , same excutable names and default install
| | path or is there more to it?
| | 
| | I do not mind compiling from source etc; actually part of joining this
| | email group was to get a sense of what was the "standard approach" that
| | is used for ubuntu and development versions of R. I also wanted to get a
| | feel for ess compatibility with the development version of R. 
| | 
| | So summary
| | 1) I can't just install the stable and development versions  from deb
| | files and have them play nice ?
| Sure. But not from .deb files as you can have exactly one R binary at the
| same time.
| [ But you can use that for the default R and then keep a bleeding edge one in
| /usr/local too. ]
| | 2) I can't compile from source code without secret sauce?
| Sure you can. It just won't be as integrated as the pre-packaged version.
| | I don't agree there should be a test for who can use the ubuntu
| | development version , it is development and unstable as so no one can
| | reasonable expect it to be foolproof. General direction are all that
| | anyone could reasonably expect.
| Most of us do not perceive Ubuntu to be the 'developer distro'.  It really is
| easy enough to split this over several different machines too.  I.e. under my
| desk is an Ubuntu box driving the desktop and a headless Debian box
| supporting additional development work.  There are many possible approaches.
| What we attempt to provide for Ubuntu is a mainstream package to satisfy
| users of the _currently released_ R versions.
| Everybody is invited (and welcone) to start their own project for packages of
| a development version.  But I think you just cannpt expect already-busy
| volunteers like Vincent, Michael or myself to do it for you.

| | | 
| | | I do not use bioconductor, so I have to ask how many packages are

| | | for public release?   I visited the web site, and there is a devel
| | | branch.  Are all of those packages built against R 2.9?
| | | 
| | | My personal opinion is that we should not follow the google definition
| | | of beta, and reserve the tag for testing purposes.  If you want to
| | | test the beta version, there should be a minimum amount of "expertise"
| | | required for entry.  For Ubuntu, having to compile from source could
| | | be that bar.  We could supply directions on how to build from the deb
| | | source packages.  It would probably need a script that makes the
| | | corrections needed to compile under Ubuntu.
| | 
| | I agree. I think we should not push down 2.9.0 on all Ubuntu users. 
| | 
| | Paul, given that Debian does have the 2.9.0 deb files ready
| | for the picking, you could also try a chroot or virtual machine running
| | Debian unstable.  By using a virtual machine (like virtualbox, very easy to
| | set up in stock Ubuntu) you get a way to have the bleeding edge software
| | running on your system without affecting the general stability of your
| | system.
| | 
| | Otherwise, take the Debian .deb source and ask us for help with local package
| | builds based on those source (as e.g. right now where Debian's package has a
| | debian/rules which uses dh_prep which you need to turn back to dh_clean etc
| | pp).  I sometimes do that at work (eg to get current Debian MPI packages onto
| | Ubuntu etc).
