readCitationFile encoding

Hi,

does anybody know, how to enforce a certain encoding for
readCitationFile()? Haven't found any usable documentation for this :(

E.g.:
basecit <- system.file("CITATION", package="base")
source(basecit, echo=TRUE, encoding="8859-1")
readCitationFile(basecit)

BTW: 'make check' is a relativ long running task and if one changes
a source file, all checks are ran again til it gets to the code in
question (in my case tests/Examples/utils-Ex.Rout.fail). Is there
a shortcut to jump immediately to the utils tests?

Regards,
jel.

Really?

From the help file in current versions of R (2.10.1 patched, 
R-devel)

     ?readCitationFile? make use of the ?encoding? element (if any) of
     ?meta? to determine the encoding of the file.

so
readCitationFile(basecit, list(encoding="latin1"))

is probably what you are looking for.  And PLEASE do use the 
recommended portable encoding names.

No, but many sections can be suppressed -- see check --help and the 
environment variables discussed in the R Internals manual.

Yes. Well, just started to dive into R and that's probably the problem
(like in old UNIX times), the help aka man pages are very useful and
sufficient, if you know the language/system ... ;-)

Ah - ok, haven't applied the latest release.diff. But anyway, for a
newbie it is not easy to find out, what "meta" is expected to be.

so
readCitationFile(basecit, list(encoding="latin1"))

Yepp - with a leading uppercase E it works. Thanx a lot!!! :)

OT: Wondering, what does "recommended portable encoding names" in this
context mean (e.g. AFAIK 'latin1' is not a standardized name ...).

BTW: Just build R-2.10.1 on Solaris Nevada b129 (x86_64) using its native
iconv facilities in libc and sunperf libs (wrt. BLAS/LAPACK) only. It
works now and all checks are saying, everything is ok.

Ahh - good hint - help("check") wasn't really fruitful. However,

elkner.idev2 build/R-2.10.1/bin > ./check --help
Can't locate File/Copy/Recursive.pm in @INC (@INC contains: ...

So still need to do a little bit tweaking ...
