Most likely you have a corrupted tarball, so I would compare its size
with that on the CRAN master (which to me looks like 680366 bytes).

By default, my R functions run silently if NA is encountered? I would
like them to give me some message when NA is encountered by default.
Note that I could check each intermediate variable by something like
is.na(). But this is not manageable for big programs, so I'd like a
way to check NA global
