generate_uuid()
generates a universally unique identifier (UUID Version
4 and Variant 1).
generate_uuid(seed = NULL)
A single integer
specifying the seeds.
If NULL
(the default) the seed will be re-initialized.
A character
string (UUID).
A 36 characters long character
string.
As it relies on R's internal random number generators and so will suffer
from the use of set.seed()
in a session, the seed is re-initialized during
execution (unless seed
is not NULL
). To prevent any side effects, the
random number generator (RNG) state is saved and restored when the function
exits.
