[R-pkg-devel] how to prevent a small package from yielding a large installed size?

[Daniel Kelley]

Duncan, thanks very much for that very helpful hint.  I got as follows.  My guess is that the first column in rdx$variables is an address offset, and so it seems that the lion's share of the storage is dedicated to items with names starting with a decimal point.  For example, the "[[" item is at offset of nearly 4M.  I may try fiddling with my code in which I specialize that method, to see whether I can reduce the memory footprint.  From what I can gather, both linux and windows build argoFloats into a package with R directory of about 2.5M size, which is a lot better than what I get in macOS but still over the warning threshold (I think) and therefore I worry about CRAN acceptance.
