Arguments

x	Object to be converted.
...	Arguments passed on to submethods
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
crs	A crs object
closed	logical; whether to treat a point sequence as a closed polygon. Default: FALSE

Value

An fm_segm or fm_segm_list object

Functions

• fm_as_segm(): Convert an object to fm_segm.

• fm_as_segm_list(): Convert each element, making a fm_segm_list object
