Value

fm_as_sfc: An sfc_MULTIPOLYGON or sfc_POLYGON object

fm_as_inla_mesh: An inla.mesh mesh object

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
