R package ctmcmove. Software to facilitates taking movement data in xyt format and pairing it with raster covariates within a continuous time Markov chain (CTMC) framework. As described in Hanks et al. (2015) &lt;<a href=”http://dx.doi.org/10.1214/14-AOAS803”>doi:10.1214/14-AOAS803</a>&gt; , this allows flexible modeling of movement in response to covariates (or covariate gradients) with model fitting possible within a Poisson GLM framework.
