Arguments

x

An object to be coerced/transformed/converted into another class

...

Arguments passed on to other methods

multi

logical; if TRUE, attempt to a sfc_MULTIPOLYGON, otherwise a set of sfc_POLYGON. Default FALSE

reverse

logical; When TRUE, reverse the order of the input points. Default FALSE

grp

if non-null, should be an integer vector of grouping labels for one for each segment. Default NULL

is.bnd

logical; if TRUE, set the boundary flag for the segments. Default TRUE

join

logical; if TRUE, join input segments with common vertices. Default TRUE

sp

An sp style S4 object to be converted

crs

A crs object

closed

logical; whether to treat a point sequence as a closed polygon. Default: FALSE

Value

  • fm_as_sfc: An sfc_MULTIPOLYGON or sfc_POLYGON object

  • fm_as_inla_mesh: An inla.mesh mesh object
