actions: Extract Metapop management action details

In mptools: RAMAS Metapop Tools

Description

Extract management action details from RAMAS Metapop .mp files.

Usage

actions(mp)

Arguments

mp	A character string containing the path to a RAMAS Metapop .mp file.

Value

A data.frame containing one row per management action, with columns:

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<thr1 or N<thr1_and_N>thr2, this is the abundance threshold thr1.
thr2	If condition is either N>thr2 or N<thr1_and_N>thr2, 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.
