rCAT (version 0.1.6)

ConBatch: Batch process, preliminary conservation assessments

Description

Combines all of routines in rCAT to process multiple species for AOO, EOO etc.

Usage

ConBatch(taxa, lat, long, cellsize, project2gether)

Arguments

taxa

field which defines a list of species or taxa

lat

field which defines the latitude set of points

long

field which defines the longtitude set of points

cellsize

cell length in metres used to for AOO projection N.B. IUCN recommend 2000 m (ie 2 km)

project2gether

TRUE or FALSE, TRUE all data is projected together using the centre of all latitudes and longtitudes. FALSE each species is projected separately. Default = FALSE

Value

dataframe with; taxa ,Number of points, Area of the enclosing recetangle, EOO Area in km2, AOO area in km2, EOO IUCN category, AOO IUCN category

	taxa	NOP	MER	EOOkm2	AOO2km	EOOcat	AOOcat
1	species x	14	918562.259811711	585915.607417865	14	LC	EN
2	species y	124	1717224.64389286	634149.482670821	124	LC	EN
3	species z	61	22622717.2314339	17839113.1220552	61	LC	EN
4	species w	1130	509390660.388499	506445176.073246	1130	LC	VU

Details

This function expects a list of taxa and latitudes and longitudes.ie

species_w	85.388000	84.33100
species_w	-45.467000	88.41500
species_w	-34.339000	-149.52600
species_x	-29.620000	79.11900
species_x	33.409000	-33.94700
species_x	64.692000	-149.18900
species_y	2.308000	-140.21900
species_y	41.452000	-3.65600
species_y	-30.475000	-129.99600
