[R-pkg-devel] Minimizing package size containing Shiny app > 5 Mb

[P Roebuck]

As recommended elsewhere, create a data-only package (which works well for
Bioinformatics projects),
perhaps named "FooSampleData". But I would hesitate recommending CRAN,
which I would have
considered better suited for general appeal packages -- these type packages
are more related to
Bioconductor, or residing in your company/university bioinformatics website
(accessible via public URL).

See the link below for an example package containing RPPA data.
