inla.mesh.assessment {INLA} | R Documentation

## Interactive mesh building and diagnostics

### Description

Assess the finite element approximation errors in a mesh for interactive R sessions. More detailed assessment tools are in `meshbuilder()`.

### Usage

    inla.mesh.assessment(mesh, spatial.range, alpha = 2, dims = c(500, 500))

### Arguments

`mesh` | An `inla.mesh`
`spatial.range` | numeric; the spatial range parameter to use for the assessment
`alpha` | numeric; A valid `inla.spde2.pcmatern` `alpha` parameter
`dims` | 2-numeric; the grid size
