Arguments

Value

do.action: Logical. Will the action be performed (TRUE) or ignored (FALSE).
action: Factor. The type of action to be performed.
sourcepop: The identity of the source population.
targetpop: The identity of the target population.
start: The timestep at which the action will commence.
end: The timestep at which the action will end.
freq: The frequency of the action, in timestep units.
after.dispersal: Logical. Whether the action will be performed after (TRUE) or before (FALSE) dispersal has taken place.
quantity: Factor. Whether the action affects an absolute number of individuals, or a proportion of the source population.
number: The absolute number of individuals involved in the action.
proportion: The proportion of the source population involved in the action.
fromstage: The lowest stage involved in the action.
tostage: The highest stage involved in the action.
condition: The condition under which the action will be performed.
thr1: If condition is either N or Nthr2, this is the abundance threshold thr1.
thr2: If condition is either N>thr2 or Nthr2, this is the abundance threshold thr2.
unknownfield: Unknown.
linear.to: If condition is linear, this is the upper quantity (absolute number, or proportion, depending on quantity) towards which linear change will move.
linear.lowerN: If condition is linear, this is the abundance at which the quantity affected is equal to number or proportion, depending on the value of quantity.
linear.upperN: If condition is linear, this is the abundance at which the quantity affected is equal to linear.to.
N.comprises.stages: Factor. The stages included in the definition of N, when calculating thr1, thr2, linear.lowerN and linear.upperN.
N.comprises.pops: Factor. The populations included in the definition of N, when calculating thr1, thr2, linear.lowerN and linear.upperN.
