Draw violin plots

circos.violin(value, pos, violin_width = 0.8,
    col = NA, border = "black", lwd = par("lwd"), lty = par("lty"),
    show_quantile = TRUE, pt.col = par("col"), cex = par("cex"), pch = 16,
    max_density = NULL, sector.index = get.current.sector.index(),
    track.index = get.current.track.index())

Arguments

value	A numeric vector, a matrix or a list. If it is a matrix, boxplots are made by columns.
pos	Positions of the boxes.
violin_width	Width of violins.
col	Filled color of boxes.
border	Color for the border as well as the quantile lines.
lwd	Line width.
lty	Line style
show_quantile	Whether to show the quantile lines.
cex	Point size.
pch	Point type.
pt.col	Point color
max_density	The maximal density value across several violins. It is used to compare between violins.
sector.index	Index of sector.
track.index	Index of track.

Examples

# \donttest{
circos.initialize(letters[1:4], xlim = c(0, 10))
circos.track(ylim = c(0, 1), panel.fun = function(x, y) {
    for(pos in seq(0.5, 9.5, by = 1)) {
        value = runif(10)
        circos.violin(value, pos)
    }
})
circos.clear()

circos.initialize(letters[1:4], xlim = c(0, 10))
circos.track(ylim = c(0, 1), panel.fun = function(x, y) {
    value = replicate(runif(10), n = 10, simplify = FALSE)
    circos.violin(value, 1:10 - 0.5, col = 1:10)
