In bRacatus: A Method to Estimate the Accuracy and Biogeographical Status of Georeferenced Biological Data

signalCalculation

Description

Calculates signals sent from reference regions to point records.

Usage

signalCalculation(ref_reg, pts, biogeo = TRUE)

Arguments

ref_reg	a list of shapefiles containing checklist regions as "presence", "native", and "alien" categories. These can be original checklists, or checklists derived from range maps.
pts	data.frame containing the point records and their coordinates.
biogeo	logical, whether the biogeographical status indices should be calculated or not. Default is true, however at least the native reference regions must be included in the data.

Value

The data.frame of species occurrences with extra columns containing the location ID and presence signals for each point. If biogeo=TRUE, the data.frame also includes the nativeness and alienness indices.
