report_mig-class: Migration report for one DC, one species and one stage

In stacomiR: Fish Migration Monitoring

Migration report for one DC, one species and one stage

Description

This class performs a migration summary. A migration monitoring operation can correspond to a single horodate (in the case of some video monitoring operation) or comprise a period which does not necessarily span a full day. The daily migration is calculated by splitting the operation between days, and the migration is either grouped or split according to the lenth of the different time spans.

Slots

dc

Object of class ref_dc-class: the control device

taxa

Object of class ref_taxa-class: the species

stage

Object of class ref_stage-class : the stage of the fish

timestep

Object of class ref_timestep_daily-class : the time step constrained to daily value and 365 days

data

Object of class data.frame with data filled in from the connect method

calcdata

A "list" of calculated daily data, one per dc, filled in by the calcule method

coef_conversion

A data.frame of daily weight to number conversion coefficients, filled in by the connect method if any weight are found in the data slot.

time.sequence

Object of class POSIXct : a time sequence of days generated by the calcule method

Note

In practise, the report_mig class uses methods (calcule, connect...) from the more elaborate report_mig_mult-class
