A utility function that aims to streamline the set up
of the required future backend with sensible defaults for most users of regional_epinow.
More advanced users are recommended to setup their own future backend based on their
available resources.
setup_future(
reported_cases,
strategies = c("multiprocess", "multiprocess"),
min_cores_per_worker = 4
)A data frame of confirmed cases (confirm) by date (date), and region (region).
A vector length 1 to 2 of strategies to pass to future::plan. Nesting
of parallisation is from the top level down. The default is to set up nesting parallisation
with both using future::multiprocess. For single level parallisation use a single strategy
or future::plan directly. See ?future::plan for options.
Numeric, the minimum number of cores per worker. Defaults to 4 which assumes 4 MCMC chains are in use per region.
Numeric number of cores to use per worker. If greater than 1 pass to
stan_args = list(cores = "output from setup future") or use future = TRUE. If only a single strategy is
used then nothing is returned.
