crawl: Fit Continuous-Time Correlated Random Walk Models to Animal Movement Data

The Correlated Random Walk Library of R functions was designed for fitting continuous-time correlated random walk models with time indexed covariates. The model is fit using the Kalman-filter on a state space version of the continuous-time stochastic movement process.
