Creates sunburst diagram using ggplot2.

Creates sunburst diagram using ggplot2.

ggSunburst(
  plotdata,
  fontsize = 1,
  rotate90 = NULL,
  maxCharacters = 30,
  legendTitle = "color",
  start = 0,
  end = NULL,
  clip = "off",
  expand = FALSE,
  ...
)

Arguments

plotdata

A data.frame.

fontsize

Default fontsize.

rotate90

Rotate the labels 90 degree or not. Default NULL will try to auto rotate the labels according the space.

maxCharacters

Maximal number of characters for labels

legendTitle

The title of the legend.

start, end

Offset of starting or ending point from 12 o'clock in radians. see coord_radial.

clip

Should drawing be clipped to the extent of the plot panel? Default "on" means yes.

expand

If TRUE, adds a small expansion factor the the limits to prevent overlap between data and axes. If FALSE, the default, limits are taken directly from the scale.

...

Other parameters (except theta) passed to coord_radial.

Value

A ggplot object

Examples

plotdata <- data.frame(
    id = c("GO:0023052", "GO:0007267", "GO:0099536", "GO:0099537", "GO:0098916"),
    x = 0.5,
    y = seq.int(5),
    xmin = 0,
    ymin = c(0.5, 1.5, 2.5, 3.5, 4.5),
    xmax = 1,
    ymax = c(1.5, 2.5, 3.5, 4.5, 5.5),
    fill = seq(1, 5),
    label = c(
        "signaling", "cell-cell signaling", "synaptic signaling",
        "trans-synaptic signaling", "anterograde trans-synaptic signaling"
    )
)
