Details

Sites can be cell indices as a numeric vector, or you can specify sites = 'all' to get all grid cells. If the epmGrid object is hexagon-based, then all grid cells that are occupied are returned. If the epmGrid is square-based, then all grid cells, occupied or empty, are returned.

Examples

tamiasEPM

# from cell indices
cells <- c(2703, 90, 3112, 179)
coordsFromEpmGrid(tamiasEPM, cells)

# for all grid cells
dim(coordsFromEpmGrid(tamiasEPM, 'all'))
