R CMD check: Locale not set to C?
...if I run "R CMD check" I get the ERROR.
Therefore; are the locales really set to "C" for "R CMD check"?
If yes; why would the example above not work?
If no; how could I achieve custom locale settings?
Thanks!

[PATCH v2 00/27] x86: PIE support and option to extend KASLR randomization
Changes:
- patch v2:
- Adapt patch to work post KPTI and compiler changes
- Redo all performance testing with latest configs and compilers
- Simplify mov macro on PIE (MOVABS now)
- Reduce GOT footprint
- patch v1:
- Simplify ftrace implementation.
- Use gcc mstack-protector-guard-reg=%gs with PIE when possible.
- rfc v3:
- Use --emit-relocs instead of -pie to reduce

x86: PIE support and option to extend KASLR randomization
These patches make the changes necessary to build the kernel as Position
Independent Executable (PIE) on x86_64. A PIE kernel can be relocated below
the top 2G of the virtual address space. It allows to optionally extend the
KASLR randomization range from 1G to 3G.
Thanks a lot to Ard Biesheuvel & Kees Cook on their feedback on compiler
changes, PIE support and KASLR in general. Thanks to

[patch 00/28]xen: Xen implementation for paravirt_ops
Hi Andi,
This series of patches implements the Xen paravirt-ops interface. It
applies to 2.6.21-git13 + patches-2.6.21-git7-070507-1.tar.gz (I think
"unwinder" is the only patch which doesn't apply to git13, and the
sched-clock patches are the only ones which this series actually
needs).
Changes since the last posting:
- More netfront review and cleanup
- Added ability to
