signal_not_recalculated: Signal that a rate array was not recalculated because it is...

In mizer: Dynamic Multi-Species Size Spectrum Modelling

Signal that a rate array was not recalculated because it is frozen

Description

Raised by the rate setters when they leave a frozen array alone although the species parameters say that it should have a different value. It is reported as a message, and info_level = 0 silences it along with the other information. Where no handler is collecting, for example when a rate setter is called directly rather than via setParams(), it is shown anyway, because it may then be all the user hears. The stronger signal_frozen() warning is raised elsewhere, by whoever knows that the user asked for a change, see signal_frozen_changes().

Usage

signal_not_recalculated(
  var,
  quantity,
  reset_call,
  derived_from = "species parameters"
)

Arguments

var	A string naming the slot that was not recalculated.
quantity	A string naming the quantity for the user, for example "metabolic rate".
reset_call	A string with the call that recalculates the quantity, for example "setMetabolicRate(params, reset = TRUE)".
derived_from	A string naming the parameters that the quantity would have been calculated from.

Value

NULL invisibly. Called for its side effect of signalling.

Examples

with_info_level(
    signal_not_recalculated("metab", "metabolic rate",
                            "setMetabolicRate(params, reset = TRUE)")
)
