Aggregate datacube over grid cell to create new dataframe with species list per grid
Source:R/aggregate_cube.R
aggregate_cube.Rd
This function aggregates a provided datacube over grid cell id, so that a new
datacube is outputted with 3 variables that contain the lists of species that
are observed for each grid cell (as speciesKeys
, ott_id
's and names).
Arguments
- mcube
An occurrence datacube with appended
ott_id
's, as produced by theappend_ott_id()
function- timegroup
An integer, representing the number of years by which you want to group your occurrence data
