unmarkedFrameOccuMulti {unmarked} | R Documentation |
Organizes detection, non-detection data for multiple species along
with the covariates. This S4 class is required by the data argument
of occuMulti

A list (optionally a named list) of length S where each element is an MxJ matrix of the detection, non-detection data for one species, where M is the number of sites, J is the maximum number of sampling periods per site, and S is the number of species in the analysis. |
