Package: r-base-core
Version: 3.0.1-3~squeezecran3.0
Severity: normal
The failure to load the datasets, as well as the wrong behaviour of sub depends
on
the locale settings. I get correct behaviour when exporting LANG=de_DE.UTF-8
before
starting R. R 2.11.1 from squeeze is not affected. However, this happens with my
backports of R 3.0.1 to squeeze as well as in a sid chroot.

I believe the behaviour of sub() (it behaves incorrectly with an empty $LANG)
should not depend on the locale setting.
For anyone interested, this may or may not be related to R bug
https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14408
and its duplicate
https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14984
for which a workaround has been introduced in R 2.14.2. Citing the NEWS file
There is a partial workaround for errors in the TRE regular-expressions
engine with named classes and repeat counts of at least 2 in a MBCS
locale (PR#14408): these are avoided when TRE is in 8-bit mode (e.g. for
useBytes = TRUE and when all the data are ASCII).
There is a hint in the R bugzilla that the problem causing this bug (#695411)
can be avoided when the
original TRE sources are used instead of the version shipped with R:
https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=15087 (comment 1)
(all?) changes introduced in the R version of TRE are documented here:
https://svn.r-project.org/R/trunk/src/extra/tre/R_changes
Some more information can be found in the log files
svn log -v https://svn.r-project.org/R/trunk/src/extra/tre
Maybe it is also of interest that the TRE author appears to be active again:
https://github.com/laurikari/tre
At the moment, it seems to me that TRE should not be the default regular
expression engine on ARM, as its behaviour depends on the value of $LANG
(probably only on the character map, UTF-8 or not), leading to this bug, but
most probably also to other problems that may be more difficult to spot.
Kind regards,
Johannes
