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.
