[Rd] Quick notes on R with F7

Hi all,

Just a quick heads up that I made the plunge into F7 this week.

R version 2.5.0 Patched (2007-06-05 r41831) compiles and passes make check-all. F7 is using:

[marcs_at_Bellerophon ~]$ gcc --version
gcc (GCC) 4.1.2 20070502 (Red Hat 4.1.2-12)

Some quick F7 notes:

  1. Do a clean install rather than an 'in place' upgrade from FC6 or a prior version. There are a lot of changes, not the least of which is the consolidation of Extras and Core into a single release.
  2. There will be some '.fc6' suffixed RPMS installed if there were no changes from the FC6 versions. I have 91 of them, out of a total of 1545 installed RPMS. Note that the F7 version RPM suffix is 'fc7', not 'f7' ...
  3. There are some issues with SELinux and policies, so I have reverted to running in 'Permissive' mode for the time being.
  4. Do not use 'rhgb' (the Red Hat Graphical Boot) on the kernel boot parameters in grub.conf. Especially if (like me) there are boot time prompts (such as dmcrypt-LUKS passphrases) that need to be input during boot. This interaction requires going from graphical to text mode and back, presumably switching virtual terminals. This may be unique to nVidia based video hardware, but there seems to be some issues with VT switching, which also seems to cause problems for the 'Fast User Switching' features new to F7. The symptoms include partially drawn windows, incomplete logins and X freezes.
  5. Emacs 22 has been released and is part of F7. From a quick look, it would appear that the 'xft/anti-aliasing' font support available from the CVS branch of 22 is not part of the formal stable release tree. Thus I will continue to use the version 23 Unicode branch from CVS, along with the latest ECB (cvs snap) and CEDET (1.0pre4 was just released today) tool versions.
  6. The rumors/intentions of TeXLive being part of F7 were premature and teTeX is still in place. This is apparently due to the decision on the part of the Fedora leadership folks that TeXLive is not yet ready for prime time.

Other than that, things seem to be well, but I suspect that there will be many updates coming in the first 30 days or so...the Fedora lists have been quite busy...

HTH, Marc Schwartz
