circos.yaxis: Draw y-axis

In circlize: Circular Visualization

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()
