Re: [Rd] SVN vs DVCS
I think the main advantage of a DVCS is that it allows many many people to make changes to a project and to integrate those changes in a non-insane way. Given that R as a very restricted list of people who actually make changes to the source, it doesn't seem that something like git or Hg would provide a major advantage. If the people on that list are happy with SVN then there's not much else to say. However, if it were thought that maybe we want more people submitting patches/making changes, then perhaps it might make more sense to move to a DVCS. I use git for everything mainly because it's *fast* and it has much better tools for viewing changes/patches and revision history. For example, 'git bisect' has allowed me track down bugs that would have been very painful for me because I'm not intimately familiar with the entire R source code. -roger On Wed, May 26, 2010 at 1:14 PM, Seth Falcon wrote: > On 5/26/10 4:16 AM, Gabor Grothendieck wrote: >> >> Note that one can also use any of the dvcs systems without actually >> moving from svn by using the dvcs (or associated extension/addon) as >> an svn client or by using it on an svn checkout. > > FWIW, I have been using git for several years now as my vsc of choice and > use it for all svn-backed projects (R included) via git-svn. > > Some of the things I like: > > - Being able to organize changes in local commits that can be revised, > reordered, rebased prior to publishing.

Re: [Rd] SVN vs DVCS
One small technical note: Simon said > That (non-linear history) is IMHO the biggest drawback of DVCS because > that means there is no way to link a particular build to the source > status and you cannot use globally valid build numbers. In mercurial (Hg) a particular snapshot can be labeled with a tag, and then referred to by that name in the future. This problem and solution is discussed in a tutorial on Mecurial (http://hginit.com/, section on "repository architecture"), precisely for matching the archive state to a software release. I can't speak to any other DVCS package. Terry Therneau __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Thanks for the info, I'm happy to use the new httpd server that serves the help files - that'd definitely help. My difficulty with this approach is that I'm not sure how to get the URL - Say for example I've done help.start(), then I do: help(plot) it will redirect my web browser to the plot page - How can I stop it touching my web browser and instead return to me the URL.
