❯ checking data for ASCII and uncompressed saves ... WARNING
Note: significantly better compression could be obtained
by using R CMD build --resave-data

gene_length_list.rda 16Kb 11Kb xz

This is resolve by setting the LazyDataCompression field in the DESCRIPTION file.
Solution found here.
I chose gzip, though it's possible other formats are more efficient:

With this, ThreeWayTest now passses checks with only a note about the size (which is ok for now):
