Draw segments through pairwise of points

circos.segments(
    x0, y0, x1, y1,
    sector.index = get.current.sector.index(),
    track.index = get.current.track.index(),
    straight = FALSE,
    col = par("col"),
    lwd = par("lwd"),
    lty = par("lty"),
    ...)

Arguments

x0

x coordinates for starting points.
y0

y coordinates for ending points.
x1

x coordinates for starting points.
y1

y coordinates for ending points.
sector.index

Index for the sector.
track.index

Index for the track.
straight

Whether the segment is a straight line.
col

Color of the segments.
lwd

Line width of the segments.
lty

Line type of the segments.
...

Pass to lines.

Examples

circos.initialize(letters[1:8], xlim = c(0, 1))
circos.track(ylim = c(0, 1), track.height = 0.3, panel.fun = function(x, y) {
    x = seq(0.2, 0.8, by = 0.2)
    y = seq(0.2, 0.8, by = 0.2)

circos.segments(x, 0.1, x, 0.9)
    circos.segments(0.1, y, 0.9, y)
})
circos.clear()
