sfc_segments: Coordinates of the points on the curve

In sfcurve: 2x2, 3x3 and Nxn Space-Filling Curves

Coordinates of the points on the curve

Description

Coordinates of the points on the curve

Usage

## S4 method for signature 'sfc_nxn'
sfc_segments(p, bases = p@rules@bases, start = c(0, 0), ...)

## S4 method for signature 'sfc_sequence'
sfc_segments(p, bases = NULL, start = c(0, 0), by = "Cpp")

Arguments

p	An sfc_nxn or sfc_sequence object.
bases	A list of base patterns, consider to use BASE_LIST.
start	Coordinate of the start point.
...	Other argument.
by	Which implementation? Only for the testing purpose.

Details

For the sfc_segments() on the sfc_sequence object, if bases is not set, it uses BASE_LIST internally. Make sure the sequence only contains the pre-defined base patterns.

Value

A two-column matrix of coordinates of points on the curve.

Examples

p = sfc_2x2("I", "11")
loc = sfc_segments(p)
plot(loc, type = "l", asp = 1)
