In ctmcmove: Modeling Animal Movement with Continuous-Time Discrete-Space Markov Chains

Description

seal$locs contains xyt locations for ARGOS fixes on the seal's location in the "datetime", "latitude", and "longitude" columns.

seal$cov.df contains a data.frame of spatial covariate values for sea surface temperature (sst), chlorophyll A levels (chA) and net primary production (npp).

Usage

data("seal")
