[Bioc-devel] Can ExperimentHub packages contain non-R data formats?

It depends on what you mean.  We include those as our load methods generally are loading files into R for immediate use by a package.

RDataClass,
DispatchClass
RDataPath


If using the Bioconductor ExperimentHub -

We can always create a new DispathClass if one existing isn't appropriate.

The RDataPath is really what we call the folder and file name on the server. We require it to be the packagename/<optional sub dir>/fileName.ext .  The files don't have to be hosted on our S3 as long as they are on a publically accessible site (This is controlled by location_prefix)

The RDataClass gives and idea of what the user will get back.  We recently added a DispathClass of FilePath so that raw files could be stored.  The output for using this DispathClass is character as you would only get a character representing the path to the raw file in the ExperimentHub cache.


Hope this helps.  Let me know if you need further assistance or any further questions.

Asking for a friend :)

The vignette [1] seems not completely explicit about this, and the
example [2] contains mandatory-looking(?) columns RDataClass,
DispatchClass, RDataPath.
