bzip2'ed data under data/

Hi,

R CMD check PACKAGE_VERSION_tar.gz gives warning:

Files not of a type allowed in a ?data? directory:
   ?tser1.csv.bz2? ?tser2.csv.bz2?
Please use e.g. ?inst/extdata? for non-R data files

which I didn't expect, based on section 1.1.5 (Data in packages) of the
Writing R Extensions manual:

Tables (`.tab', `.txt', or `.csv' files) can be compressed by
`gzip', `bzip2' or `xz', optionally with additional extension `.gz',
`.bz2' or `.xz'.  However, such files can only be used with R 2.10.0 or
later, and so the package should have an appropriate `Depends' entry in
its DESCRIPTION file.

In this case, I have a Depends: R (>= 2.13.0), and the package was built
with R version 2.15.0 beta (2012-03-16 r58769), Platform:
x86_64-pc-linux-gnu (64-bit), so I don't understand the warning.

Cheers,

Well, the extension is allowed 'optionally' to be .csv.bz2, but that
does not make it good practice and I would suggest not using it.

But that 'check' picked it up was a typo in the code 'check' used to
specify types of data() files, corrected since your build of R so I
would expect current R-devel or R-pre-release not to give the NOTE.  I
am not sure whether or not that has any ramifications for users of the
package with older versions of R, but we know calling the compressed
file foo.csv would work.

Does this mean we can still compress the files, but leave the file name
with suffix *.csv (i.e. not adding the compression-specific suffix)?
The 2 files I'm including in the package are a little over 1 Mb, and
bzip2 gets them down to<  150 Kb.

Up to R 2.14.2, R CMD check was reporting a Warning, rather than a Note,
but indeed the latest R-devel and R-pre-release don't.  Thanks.

Yes, that is what the help file says.
