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

`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`.

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