siteSelectionMinL: List-length site selection

In BiologicalRecordsCentre/sparta: Trend Analysis for Unstructured Data

List-length site selection

Description

This function uses part of the method outlined in Roy et al (2012) and Isaac et al (2014) for selecting well-sampled sites from a dataset using list length only. siteSelection is a wrapper for this function that performs the complete site selection process as outlined in these papers.

Usage

siteSelectionMinL(taxa, site, time_period, minL)

Arguments

taxa	A character vector of taxon names
site	A character vector of site names
time_period	Anumeric vector of user defined time periods, or a date vector
minL	numeric, The minimum number of taxa recorded at a site at a given time period (list-length) for the visit to be considered well sampled.

Value

A data.frame of data that forefills the selection criteria. This data has two attributes: visits gives the total number of visits in the dataset (unique combinations of site and time_period), success gives the number of visits that satify the selection criteria
