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, ...)

## S3 method for class 'SpatialPoints'
as.inla.mesh.segment(sp, reverse = FALSE, grp = NULL, is.bnd = TRUE, ...)

## S3 method for class 'SpatialPointsDataFrame'
as.inla.mesh.segment(sp, ...)

## 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 'SpatialPolygons'
as.inla.mesh.segment(sp, join = TRUE, grp = NULL, ...)

## S3 method for class 'SpatialPolygonsDataFrame'
as.inla.mesh.segment(sp, ...)

## S3 method for class 'Polygons'
as.inla.mesh.segment(sp, join = TRUE, crs = NULL, ...)

## S3 method for class 'Polygon'
as.inla.mesh.segment(sp, crs = NULL, ...)

Arguments

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

Value

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