R: Convert 'sp' curve objects to 'inla.mesh.segment' objects.

as.inla.mesh.segment {INLA}

R Documentation

Convert `sp` curve objects to `inla.mesh.segment` objects.

Description

Convert sp curve objects to inla.mesh.segment objects.

Usage

as.inla.mesh.segment(sp, ...)
inla.sp2segment(sp, ...) ## For backwards compatibility

## S3 method for class 'Line'
as.inla.mesh.segment(sp, reverse=FALSE, crs=NULL, ...)
## S3 method for class 'Lines'
as.inla.mesh.segment(sp, join=TRUE, crs=NULL, ...)
## S3 method for class 'SpatialLines'
as.inla.mesh.segment(sp, join=TRUE, grp=NULL, ...)
## S3 method for class 'SpatialLinesDataFrame'
as.inla.mesh.segment(sp, ...)
## S3 method for class 'Polygon'
as.inla.mesh.segment(sp, crs=NULL, ...)
## S3 method for class 'Polygons'
as.inla.mesh.segment(sp, join=TRUE, crs=NULL, ...)
## S3 method for class 'SpatialPolygons'
as.inla.mesh.segment(sp, join=TRUE, grp=NULL, ...)
## S3 method for class 'SpatialPolygonsDataFrame'
as.inla.mesh.segment(sp, ...)

Arguments

`sp`	An `sp` polygon object of class `Polygon`, `Polygons`, `SpatialPolygons`, or `SpatialPolygonsDataFrame`.
`join`	If `TRUE`, join multiple polygons into a single segment (possibly non-simply connected).
`grp`	Group ID specification for each polygon, as used by `inla.mesh.segment`, one ID per polygon.
`reverse`	Logical, indicating if the line sequence should be traversed backwards.
`crs`	An optional `CRS` or `inla.CRS` object
`...`	Additional arguments passed on to other methods.

Value

A inla.mesh.segment object, or a list of inla.mesh.segment objects.
