[Rd] Accessing data files w/ --use-zip-data

Examples are the makecdfenv und matchprobes packages, part of which I
wrote. They deal with data formats that are external to R, namely vendor
(Affymetrix) specific file formats, and provide tools for importing these
data into R. For the examples / vignettes, I need to provide example data
files. Up to now I am putting them into the data directory, and access
them with

specializedImportFunction(file.path(.path.package("matchprobes"),
                          "data", "HG-U95Av2_probe_tab.gz"), ...)

Is this considered offensive to the R package structure? Whereelse to put
data that comes in specialized (not .rda, .txt, .csv) formats?

Thanks
