Observations by species or records-by-species matrix

This function prepares the organised data into a "records-by-species" matrix summarizing the number of observations (records) per species in the shape required by the functions from the KnowBR package for calculating 'completeness'.

recBySpp(x, format = "A", location = "coordinates")

Arguments

x	an object of class ‘OrganizedBirds’ (organised BIRDS Spatial Dataframe).
format	the type of matrix to return: type 'A' where each row is a combination of species, location (unique coordinates or visits' ID) and count, or 'B' where each row is a location, each column a species, and the elements of the matrix the counts
location	the uniqueness of the position given by the coordinates or the visits' ID

Value

a data.frame with a record-by-species matrix
