inla.mesh.1d {INLA} | R Documentation

## Function space definition objects for 1D SPDE models.

### Description

Use `fmesher::fm_mesh_1d()` instead.

Create a 1D mesh specification `inla.mesh.1d` object, that defines a function space for 1D SPDE models.

### Usage

    inla.mesh.1d(
      loc,
      interval = range(loc),
      boundary = NULL,
      degree = 1,
      free.clamped = FALSE,
      ...
    )

    inla.mesh.1d.fem(mesh)

### Arguments

`loc` | B-spline knot locations.
`interval` | Interval domain endpoints.
`boundary` | Boundary condition specification. Valid conditions are `c('neumann', 'dirichlet', 'free', 'cyclic')`. Two separate values can be specified, one applied to each endpoint.
`degree` | The B-spline basis degree. Supported values are 0, 1, and 2.
`free.clamped` | If `TRUE`, for `'free'` boundaries, clamp the basis functions to the interval endpoints.
`...` | Additional option, currently unused.
`mesh` | An inla.mesh.1d object

### Functions

- `inla.mesh.1d.fem()`: Use `fmesher::fm_fem()` instead.
