report_species-class: Counts of number per taxa/stages

In stacomiR: Fish Migration Monitoring

Counts of number per taxa/stages

Description

This class is used to make the assessment of all species, and their number. It is intended as a simple way to check what fishes are present (taxa + development stage). It was altered to include ref_taxa, to allow excluding some of the most numerous taxa from reports. The taxa is reported unless a taxa has several stages, in which case the different stages for the taxa will be reported Using the split arguments the calc method of the class will count numbers, subsamples are not accounted for in the Overview. The split argument currently takes values year or month. The class is intended to be used over long periods e.g years. The plot method writes either an histogram or a pie chart of number per year/week/month.
