insecticide_check: insecticide_check check if insecticide needs to be changed

In ian-hastings/rotations: Simulating the Evolution of Insecticide Resistance under Rotations

Description

based on a fixed interval no. generations, or rotate-when-resistant if interval is 0. The actual switching of insecticides is done in insecticide_switch().

Usage

insecticide_check(
  RAF1gen,
  current_insecticide,
  rot_interval,
  threshold,
  mort_or_freq,
  gens_this_insecticide,
  min_rwr_interval,
  exit_rot,
  eff,
  dom_sel,
  rr,
  change_interval,
  diagnostics = FALSE
)

Arguments

RAF1gen	single generation array of resistance allele frequencies
current_insecticide	id number of current insecticide
rot_interval	frequency of rotation (in generations) NB if set to zero mean RwR i.e. rotate when resistant
threshold	trigger for change of insecticide, either resistance frequency or mortality dependent on mort_or_freq, also precludes switch to an insecticide.
mort_or_freq	whether threshold for insecticide change is mortality 'mort' or resistance frequency 'freq'
gens_this_insecticide	num generations this insecticide has been used for
min_rwr_interval	minimum rotate-when-resistant interval to stop short switches, only used when rot_interval==0. set to 0 to have no effect.
exit_rot	whether to exit rotation interval if threshold is reached
eff	effectiveness propn. SS killed by insecticide, for all insecticides or individually
dom_sel	dominance of selection, for all insecticides or individually
rr	resistance restoration, for all insecticides or individually
change_interval	interval that insecticide can be changed on for both rotation and sequence, default 10 gens 1 year
diagnostics	whether to output running info

Value

TRUE/FALSE whether to change
