1. What is Excursions ?
Excursions is an R-package with functions for calculating excursion sets, contour credible regions, and simultaneous confidence bands, for latent Gaussian models. The package has a function that takes a result object calculated by the INLA package and calculates specified excursion sets or contour credible regions. For a latent Gaussian model estimated using INLA this function, for example, makes it easy to find the largest area where the latent process, with some given probability, is positive.
