Add line segments to Hilbert curve

# S4 method for HilbertCurve
hc_segments(object, ir = NULL, x1 = NULL, x2 = NULL,
    gp = gpar(lty = 1, lwd = 1, col = 1))

Arguments

object: A HilbertCurve-class object.
ir: an IRanges object which specifies the input intervals.
x1: if start positions are not integers, they can be set by x1.
x2: if end positions are not integers, they can be set by x2.
gp: graphic parameters for lines. It should be specified by gpar. Note you cannot set linejoin and lineend.

Value

A data frame which contains coordinates (in the 2D space) of segments.

Examples

hc = HilbertCurve(1, 100, level = 4, reference = TRUE)

x = sort(sample(100, 20))
s = x[1:10*2 - 1]
e = x[1:10*2]
require(IRanges)
ir = IRanges(s, e)

hc_segments(hc, ir)
