I’m co-maintaining bioRad, a package to analyze weather radar data for biological signals (like birds). Since a large part of the functionality is analyzing weather radar data, we included a raw data file “volume.h5” in the pkg at inst/extdata, which is used in many of the examples. We’ve reduced the file size as much as we can, but we’re exceeding the pkg size of 5Mb for CRAN submission.
I’m thinking of removing the raw files from the pkg and publishing those separately as a data pacakge on Zenodo.org, but that would mean that every example using those starts with downloading a file.
Any suggestions or other better approaches?
