Initial fishing effort
Description
The fishing effort is a named vector, specifying for each fishing gear the
effort invested into fishing with that gear. The effort value for each gear
is multiplied by the catchability and the selectivity to determine the
fishing mortality imposed by that gear, see setFishing() for more details.
A valid effort vector is a named vector with one effort value for each gear.
Usage
initial_effort(params)
initial_effort(params) <- value
validEffortVector(effort, params)
Arguments
params |
A MizerParams object |
value |
The initial fishing effort |
effort |
A vector or scalar. |
Details
The initial effort you have set can be overruled when running a simulation
by providing an effort argument to project() which allows you to
specify a time-varying effort.
The function also accepts an effort that is not yet valid:
a scalar, which is then replicated for each gear
an unnamed vector, which is then assumed to be in the same order as the gears in the params object
a named vector in which the gear names have a different order than in the params object. This is then sorted correctly.
a named vector which only supplies values for some of the gears. The effort for the other gears is then set to zero.
An effort argument will lead to an error if it is either
unnamed and of the wrong length
named but where some names do not match any of the gears
not numeric
Value
Effort vector
