With yet another e-mail by Alain Hauser about tweaks in my R package sfsmisc
I've felt the urge again, to finally move my very oldest R package to a "RCS" a "revision control system" aka "version control" system.
Now the sfsmisc package has a particular history. As its DESCRIPTION file says, also visible in the CRAN web page above, the package describes itself as
Useful utilities ['goodies'] from Seminar fuer Statistik ETH Zurich, quite a few related to graphics; many ported from S-plus times.
and so is talking about S+ code originating in the 1990s, really. Now, some may know that R's history also started then, and I got involved with it not very long after its creation by Ross Ihaka and Robert Gentleman, after they had announced it on the S-news mailing list in 1994 (we think.. nobody has found the original e-mail as far as I know).
Anyway, the "SfS goodies" (SfS := Seminar für Statistik) at the time was a directory of S (or "S-plus" or "S+") functions we had found useful at the SfS. Consequently these were among the first things ported to R by me, among them by the way, the str() function which I added to R myself in very early time:
It was part of R 0.61.0, released 1997-12-21, already.
Okay, by now, you must have grasped that I am really nostalgic about this... As a consequence, I did want to keep as much history as possible, and I did succeed in the end, but look at the steps I've used to move things to git and github:
Finally, I happily point my browser to github and eventually to

Okay, by now, you must have grasped that I am really nostalgic about this... As a consequence, I did want to keep as much history as possible, and I did succeed in the end, but look at the steps I've used to move things to git and github:
- A few of my many files in the package, I put under RCS control earlier, namely 9 files in the ./R/ subdirectory plus the prime-numbers demo, i.e. for these 10 files, there was already a corresponding foo,v file.
- For all other source files, notably those inside ./R/, I had kept numbered emacs backup files i.e. for a file foo, files named foo.~1~, foo.~2~ etc. Now these I transformed into a *,v RCS (archive) file with a new version of my shell script G2RCS, I appropriately called G2RCSn (final 'n'). In the end, a total of 146 *,v files. How did I achieve that efficiently?
- In Emacs dired (DIRectory EDitor, the supersmart file browser since the ending 1980s) I've marked all the source files (R/*.R, man/*.Rd, ...) which did not have a corresponding *,v (so from the above, I deduce, there were 146-10=136 of those) and then used "!" to call G2RCSn on those.
- Now, I had downloaded the utility rcs-fast-export.rb, a ruby script, and made it executable in my ~/bin/.
- Now, inside my ~/R/Pkgs/sfsmisc/ (and after backing up the whole source tree into a tarball) I did exactly what rcs-fast-export.rb --help tells me: git init && rcs-fast-export.rb . | git fast-import && git reset
- Using Emacs 'magit' -- the git interface Doug Bates taught me about -- which I have long assigned to C-c v I see that I have ended up with some modified files (marked with an "M "), namely those that had an $Id..$ "tag" inside. Magit also presented me my many untracked files, so I quickly got a .gitignore file so things are easier to browse. Ok, now I do use magit to change/commit afew things, notably getting rid of the $Id$ labels.
- After playing around a bit more and convincing myself things work, I remove all the *,v (and *-ss) files, as they are not needed anymore evidently.
- Now the next - basically last - step: Put the already working local git repository on github (so Alain could make a pull request, next time.. :-):
- create a repository on github (by webpage clicking)
- in the shell, inside ./sfsmisc/ , do what I found before:
git push --mirror https://github.com/mmaechler/sfsmisc.git where I do need to give my github credentials --> and whoosh! I am done.. whew! Well writing the blog really took longer than doing it! I need to get more convenient blogging infrastructure...
Finally, I happily point my browser to github and eventually to
