Add text to Hilbert curve

1 2	## S4 method for signature 'HilbertCurve' hc_text(object, ir, labels, x1 = NULL, x2 = x1, gp = gpar(), ...)

`object`	A `HilbertCurve-class` object.
`ir`	an `IRanges` object that contains positions which correspond to text. The middle point of the interval will be the position of the text.
`labels`	text corresponding to intervals in `ir`.
`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 text. It should be specified by `gpar`.
`...`	pass to `grid.text`. E.g. you can set text justification by `just` here.

The text is added correspoding to the middle of each interval in ir.

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

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

labels = sample(letters, length(ir), replace = TRUE)
hc_text(hc, ir, labels = labels)
