Description Usage Arguments Value Author(s) Examples

Generical function to get the fishing effort. The type of fishing effort could be four types:

travelTime for the effort as a function of the travel time.
haulTotal for the effort as a function of the total number of fishing haul.
storageCapacity for the effort as a function of the storage capacity.
searchTime for the effort as a function of the search time to catch the species.

1	getEffort(data, efforType, effortBy, timeBy, fleeType = NULL)

`data`	A `data.frame` with information to estimated the fishing effort (in columns). This data base have to contain columns of the time (days, months, years, season), ports and the fleet type.
`efforType`	A `character`. It could be one of the fishing effort type ("travelTime", "haulTotal", "storageCapacity", "searchTime").
`effortBy`	Parameter to indicate whether the effort will be estimated by time (`effortBy = time`) or by port (`effortBy = port`).
`timeBy`	If the effort is estimated over the time, it could be by days (`timeBy = days`), months (`timeBy = months`), years (`timeBy = years`) or by seasons (`timeBy = seasons`).
`fleeType`	The effort could be estimated for the whole data given or for a data by fleeType. By default this parameter is `NULL`.

A vector with the estimated effort.
