Generate UUIDs (Universally Unique IDentifiers). In previous
versions this was simply a thin wrapper around
uuid::UUIDgenerate, however this was subject to collisions on
windows where relatively small numbers of UUIDs generated at the
same time could return values that were identical. We now generate
only version 4 UUIDs (i.e., random though with particular bits
set).
uuid(n = 1, drop_hyphens = FALSE, use_time = NA)number of ids to return. If NULL, it instead returns
the generating function
Drop the hyphens from the UUID?
Unused.
