UNRELIABLE VALUE: Future (‘<none>’) unexpectedly generated random numbers without specifying argument 'seed'.

[OscarKjell]

I am using:
future::plan(future::multisession)
and
furrr::future_map()

Although it works, I get the following error:

UNRELIABLE VALUE: Future (‘<none>’) unexpectedly generated random numbers without specifying argument 'seed'. There is a risk that those random numbers are not statistically sound and the overall results might be invalid. To fix this, specify 'seed=TRUE'. This ensures that proper, parallel-safe random numbers are produced via the L'Ecuyer-CMRG method. To disable this check, use 'seed=NULL', or set option 'future.rng.onMisuse' to "ignore".

I do not know how/where to add seed=TRUE.

Thank you in advance!
Oscar

Hi. See ?furrr::future_map. The first example shows how to do it.
