In circlize: Circular Visualization

Add a label track

Description

Add a label track

Usage

circos.labels(
    sectors, x, labels,
    facing = "clockwise",
    niceFacing = TRUE,
    col = par("col"),
    cex = 0.8,
    font = par("font"),
    padding = 0.4,
    connection_height = mm_h(5),
    line_col = par("col"),
    line_lwd = par("lwd"),
    line_lty = par("lty"),
    labels_height = min(c(cm_h(1.5), max(strwidth(labels, cex = cex, font = font)))),
    side = c("inside", "outside"),
    labels.side = side,
    track.margin = circos.par("track.margin"))

Arguments

sectors	A vector of sector names.
x	Positions of the labels.
labels	A vector of labels.
facing	Facing of the labels. The value can only be "clockwise" or "reverse.clockwise".
niceFacing	Whether automatically adjust the facing of the labels.
col	Color for the labels.
cex	Size of the labels.
font	Font of the labels.
padding	Padding of the labels, the value is the ratio to the height of the label.
connection_height	Height of the connection track.
line_col	Color for the connection lines.
line_lwd	Line width for the connection lines.
line_lty	Line type for the connectioin lines.
labels_height	Height of the labels track.
side	Side of the labels track, is it in the inside of the track where the regions are marked?
labels.side	Same as side. It will replace side in the future versions.
track.margin	Bottom and top margins.

Details

This function creates two tracks, one for the connection lines and one for the labels.

If two labels are too close and overlap, this function automatically adjusts the positions of neighouring labels.

Examples

circos.initialize(sectors = letters[1:8], xlim = c(0, 1))
circos.track(ylim = c(0, 1))
circos.labels(c("a", "a", "b", "b"), x = c(0.1, 0.12, 0.4, 0.6), labels = c(0.1, 0.12, 0.4, 0.6))
