circos.text: Draw text in a cell

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.

circos.par(points.overflow.warning = FALSE)
circos.initialize(factors = factors, xlim = 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)

        cex = 0.8)
})
circos.clear()
