local_bru_options_set() is used to set global package options.
local_bru_options_set() returns a copy of the global override
options (not including the defaults), invisibly.
local_testthat_assign: Assign local variable. Useful for easy cleanup
of global workspace with withr::deferred_run() when running tests
interactively.
local_testthat_tolerances: Assign test tolerances
Assign local tolerance variables. Useful for easy cleanup
of global workspace with withr::deferred_run() when running tests
interactively.
local_bru_options_set: Calls bru_options_set() in a reversible way
local_set_PROJ6_warnings: Disable PROJ4/6 warnings.
To be used within package tests. Restores state on exit.
local_get_rgdal_options: Return a list of the current rgdal warning options
local_disable_PROJ6_warnings: Disable rgdal PROJ4 conversion warnings and thin
PROJ6 warnings.
local_bru_safe_inla: Tests should set num.threads = "1:1" to ensure
within-system repeatability by calling local_bru_safe_inla();
see also bru_safe_inla()
local_bru_testthat_setup: Initialise environment for tests.
Disables PROJ4/PROJ6 warnings, and assigns tolerance variables.
To be called either at the top of a testfile, or inside tests.
Does not call local_bru_safe_inla(), since that may invoke a skip and
should be called inside each test that relies on INLA.
my_fun <- function(val) {
local_bru_options_set(bru_verbose = val)

# Inside the function, the bru_verbose option is changed.
# Outside the function, the bru_verbose option is unchanged.
