The optimal choice for this now is the uuid package. It consists of one function (UUIDgenerate) that doesn't rely on R's internal random number generators and so doesn't suffer any consequences from using set.seed in a session as @thelatemail's answer does. You can choose to have the UUID be generated either by the package's internal random number generator or based on time.
