circos.text: Draw text in a cell

In 1156054203/circlize-: Circular Visualization

Description

Draw text in a cell

Usage

circos.text(x, y, labels, sector.index = get.cell.meta.data("sector.index"),
    track.index = get.cell.meta.data("track.index"), direction = NULL,
    facing = c("inside", "outside", "reverse.clockwise", "clockwise",
    "downward", "bending", "bending.inside", "bending.outside"), niceFacing = FALSE,
    adj = par("adj"), cex = 1, col = par("col"), font = par("font"), ...)

Arguments

x	Data points on x-axis
y	Data points on y-axis
labels	Labels for each points
sector.index	Index for the sector
track.index	Index for the track
direction	deprecated, use facing instead.
facing	Facing of text. Please refer to vignette for different settings
niceFacing	Should the facing of text be adjusted to fit human eyes?
adj	offset for text. By default the text position adjustment is either horizontal or vertical in the canvas coordinate system. The "circular horizontal" offset can be set as a value in degree unit and the value should be wrapped by degree.
...	Pass to text
cex	Font size
col	Font color
font	Font style

Details

The function is similar to text. All you need to note is the facing settings.

Examples

factors = letters[1:4]
circos.par(points.overflow.warning = FALSE)
circos.initialize(factors = factors, xlim = c(0, 10))
circos.trackPlotRegion(factors = factors, ylim = c(0, 10), 
  track.height = 0.5, panel.fun = function(x, y) {
    circos.text(3, 1, "inside", facing = "inside", cex = 0.8)
    circos.text(7, 1, "outside", facing = "outside", cex = 0.8)
    circos.text(0, 5, "reverse.clockwise", facing = "reverse.clockwise", 
        adj = c(0.5, 0), cex = 0.8)
    circos.text(10, 5, "clockwise", facing = "clockwise", adj = c(0.5, 0), 
        cex = 0.8)
    circos.text(5, 5, "downward", facing = "downward", cex = 0.8)
    circos.text(3, 9, "====bending.inside====", facing = "bending.inside", 
        cex = 0.8)
    circos.text(7, 9, "====bending.outside====", facing = "bending.outside", 
        cex = 0.8)
})
circos.clear()
