Constructs observation/prediction weight matrices for metric graph models.
graph_spde_basis(graph_spde, repl = NULL, drop_na = FALSE, drop_all_na = TRUE)
The observation matrix.
An inla_metric_graph_spde
object built with the
graph_spde()
function.
Which replicates? If there is no replicates, or to
use all replicates, one can set to NULL
.
Should the rows with at least one NA for one of the columns be removed? DEFAULT is FALSE
