is.na.sk

Returns a logical vector indicating which grid points have NA values assigned

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>.
