I've got a package that I'd like to submit to CRAN, but the data is huge, about 20 MB of compressed internal (used for unit tests, not exported) and about 7 MB of compressed exported data (used in vignettes).
I could maybe cut this down a bit by altering my compression but not by much. This package offers a pipeline that involves multiple manifold learning, classification, and pathway inference steps, and the testing involves high-dimensional objects (caveat: although currently in the 10 MB range, these could be made much smaller and still serve their purpose).
It's my understanding that package data (both in /data and R/sysdata.rda) should not exceed 5 MB in size. What are my options?
