Draw text in a cell — ccText • circlizePlus

Object ccCellGeom will call the function circlize::circos.text while drawing.

Usage

ccText(
  x,
  y,
  labels,
  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
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.
cex: Font size
col: Font color
font: Font style
...: Pass to text

Value

Object ccCellGeom

Examples

library(circlizePlus)
n <- 1000
df <- data.frame(
  sectors = sample(letters[1:8], n, replace = TRUE),
  x = rnorm(n), y = runif(n)
)
par1 <- ccPar("track.height" = 0.1)
cc <- ccPlot(sectors = df$sectors, x = df$x) + par1
track1 <- ccTrack(
  sectors = df$sectors, y = df$y,
  panel.fun = function(x, y) {
    circos.text(
      CELL_META$xcenter,
      CELL_META$cell.ylim[2] + mm_y(5),
      CELL_META$sector.index
    )
    circos.axis(labels.cex = 0.6)
  }
)
cell1 <- ccCell(sector.index = "a") + ccText(-1, 0.5, "text")
track1 <- track1 + cell1
cc <- cc + track1
