SRSex: Sampling representativeness score ex situ
In GapAnalysis: Conservation Indicators using Spatial Information

Description Usage Arguments Value References Examples

The SRSex process provides a general indication of the completeness of ex situ conservation collections, calculating the ratio of germplasm accessions (G) available in ex situ repositories to reference (H) records for each taxon, making use of all compiled records, regardless of whether they include coordinates, with an ideal (i.e., comprehensive) conservation ratio of 1:1. In this and in the subsequent measurements, if no G or H records exist, taxa are automatically considered to be of high priority for further conservation action and assigned a value of 0. If there are more G than H records, SRSex is set to 100.

1	SRSex(Species_list, Occurrence_data)

`Species_list`	A species list to calculate the SRSex metrics.
`Occurrence_data`	A data frame object with the species name, geographical coordinates, and type of records (G or H) for a given species

This function returns a data frame with two columns:

species	Species name
SRSex	SRSex value calculated

##Obtaining occurrences from example
data(CucurbitaData)
##Obtaining species names from the data
Cucurbita_splist <- unique(CucurbitaData$species)
#Running SRSex
SRSex_df <- SRSex(Species_list = Cucurbita_splist,
                    Occurrence_data = CucurbitaData)
