Load INLA safely for examples and tests — bru_safe

Loads the INLA package with requireNamespace("INLA", quietly = TRUE), and optionally checks and sets the multicore num.threads INLA option.

Usage

bru_safe_inla(
  multicore = NULL,
  quietly = FALSE,
  minimum_version = "23.1.31",
  .envir = NULL
)

multicore: logical; if TRUE, multiple cores are allowed, and the INLA num.threads option is not checked or altered. If FALSE, forces num.threads="1:1:1". Default: NULL, checks if running in testthat or non-interactively, in which case sets multicore=FALSE, otherwise TRUE.
quietly: logical; if FALSE and multicore is FALSE, prints a message if the num.threads option isn't already "1.1:1" to alert the user to the change. Default: FALSE.
minimum_version: character; the minimum required INLA version. Default 23.1.31 (should always match the requirement in the package DESCRIPTION)
.envir: The environment used for withr scoping. If NULL, the withr::defer() is skipped, making the options permanent within the current R session. Default: NULL

logical; TRUE if INLA was loaded safely, otherwise FALSE

if (FALSE) { # \dontrun{
if (bru_safe_inla()) {
  # Run inla dependent calculations
}
} # }
