%description
Geostatistical modeling and kriging with gridded data using spatially
separable covariance functions (Kronecker covariances). Kronecker products
in these models provide shortcuts for solving large matrix problems in
likelihood and conditional mean, making 'snapKrig' computationally
efficient with large grids. The package supplies its own S3 grid object
class, and a host of methods including plot, print, Ops, square bracket
replace/assign, and more. Our computational methods are described in Koch,
Lele, Lewis (2020) <doi:10.7939/r3-g6qb-bq70>.
