Draw y-axis

Description

Draw y-axis

Usage

circos.yaxis(
    side = c("left", "right"),
    at = NULL,
    labels = TRUE,
    tick = TRUE,
    sector.index = get.current.sector.index(),
    track.index = get.current.track.index(),
    labels.font = par("font"),
    labels.cex = par("cex"),
    labels.niceFacing = TRUE,
    tick.length = convert_x(1, "mm", sector.index, track.index),
    lwd = par("lwd"),
    col = par("col"),
    labels.col = par("col"))

Arguments

`side`	add the y-axis on the left or right of the cell
`at`	If it is numeric vector, it identifies the positions of the ticks. It can exceed `ylim` value and the exceeding part would be trimmed automatically.
`labels`	labels of the ticks. The exceeding part would be trimmed automatically. The value can also be logical (either an atomic value or a vector) which represents which labels to show.
`tick`	Whether to draw ticks.
`sector.index`	Index for the sector
`track.index`	Index for the track
`labels.font`	font style for the axis labels
`labels.cex`	font size for the axis labels
`labels.niceFacing`	Should facing of axis labels be human-easy
`tick.length`	length of the tick
`lwd`	line width for ticks
`col`	color for the axes
`labels.col`	color for the labels

Details

Note, you need to set the gap between sectors manually by circos.par to make sure there is enough space for y-axis.

Examples

op = par(no.readonly = TRUE)

sectors = letters[1:8]
circos.par(points.overflow.warning = FALSE)
circos.par(gap.degree = 8)
circos.initialize(sectors, xlim = c(0, 10))
circos.trackPlotRegion(sectors, ylim = c(0, 10), track.height = 0.5)
par(cex = 0.8)
for(a in letters[2:4]) {
  circos.yaxis(side = "left", sector.index = a)
}
for(a in letters[5:7]) {
  circos.yaxis(side = "right", sector.index = a)
}
circos.clear()

par(op)
