Return an _opts List per Region

Source: R/opts.R
opts_list.Rd

[Maturing] Define a list of _opts() to pass to regional_epinow() _opts() accepting arguments. This is useful when different settings are needed between regions within a single regional_epinow() call. Using opts_list() the defaults can be applied to all regions present with an override passed to regions as necessary (either within opts_list() or externally).

Usage

opts_list(opts, reported_cases, ...)

Arguments

opts

An _opts() function call such as rt_opts().

reported_cases

A data frame containing a region variable indicating the target regions.

...

Optional override for region defaults. See the examples for use case.

Value

A named list of options per region which can be passed to the _opt

accepting arguments of regional_epinow.
