validate_gp: Validate a GP spatial specification against data

In tulpa: Templated Unified Library for Posterior Approximation in Bayesian Hierarchical Models

Validate a GP spatial specification against data

Description

Fills in the neighbor structure (spatial_gp()) or structures (spatial_multiscale()) that tulpa_gibbs() and tulpa_laplace() need from a ⁠spatial =⁠ spec, since those design-matrix doors take no data argument to validate one themselves. tulpa() calls this internally, so it only needs to be called directly when fitting through a design-matrix door.

Usage

validate_gp(gp, data)

Arguments

gp	A spatial_gp() or spatial_multiscale() object.
data	Data frame containing the coordinate columns named in gp.

Value

Updated spatial object with computed neighbor structure.

Examples

set.seed(1)
d <- data.frame(lon = runif(30), lat = runif(30))
gp <- validate_gp(spatial_gp(~ lon + lat, nn = 5), d)
gp$n_spatial
