## S4 method for signature 'character,ANY'
rmProjectOption(id,
  where = tryCatch(devtools::as.package(".")$package, error = function(cond) {
      stop("Invalid default value for `where`") }), sub_id = character(),
  strict = c(0, 1, 2), ...)

Arguments

id

character.

where

ANY.

sub_id

character. Optional ID for a sub layer. Useful for a hub-like option container structure.

strict

logical. Controls what happens when id points to a non-existing option object:

  • 0: ignore and return FALSE to signal that the assignment process was not successful or fail_value depending on the value of return_status

  • 1: ignore and with warning and return FALSE

  • 2: ignore and with error

...

Further arguments to be passed to subsequent functions/methods.
