CellCount: Calculates degree x degree cell counts of a specified size In GeoRange: Calculating Geographic Range from Occurrence Data

Description

Calculates degree x degree cell counts of a specified size

Usage

 1 2 CellCount(longs, lats, CellSize = 5, longBounds = c(-180, 180), latBounds = c(-90, 90))

Arguments

 longs - Array of longitudinal occurrence values in decimal degrees lats - Array of latitudinal occurrence values in decimal degrees CellSize - Size of each cell in degree X degree longBounds - Array of longitudinal boundaries in decimal degrees latBounds - Array of latitudinal boundaries in decimal degrees

Value

Returns the number of cells occupied, specified cell size, and coordinate list

Note

This method uses grids cells constructed by equal degrees not area. So high latitude cells will have smaller areas than those at low latitude

Examples

 1 2 3 longs<-c(22,55,-144) lats<-c(-12,22,-12) CellCount(longs,lats,CellSize=5,longBounds=c(-180,180),latBounds=c(-90,90))
