circos.stackedText: Add a stacked text track

In jokergoo/circlize: Circular Visualization

Add a stacked text track

Description

Add a stacked text track

Usage

circos.stackedText(sectors, x, text,
    col = par("col"), font = par("font"), cex = par("cex"), family = par("family"),
    bg.border = "black", bg.col = "#FF8080",
    niceFacing = FALSE,
    side = c("outside", "inside"))

Arguments

sectors	A vector of sector names.
x	A vector of x-coordinates.
text	A vector of texts.
bg.border	Background color.
bg.col	Colors for borders.
niceFacing	Current not supported.
side	Side of the track.
col	Text colors.
font	Text fontfaces.
cex	Font sizes.
family	Font families.

Details

The height of the track is not fixed, so you may need to manually adjust the track height.

Examples

## Not run: 
circos.par$circle.margin = 0.5
circos.par$cell.padding = rep(0, 4)
circos.par$track.margin = rep(0, 2)

circos.initialize(sectors = letters[1:4], xlim = c(0, 1))

sectors = sample(letters[1:4], 40, replace = TRUE)
x = runif(40)
text = sapply(letters[sample(26, 40, replace = TRUE)], function(x) strrep(x, sample(4:6, 1)))
circos.stackedText(sectors, x, text, bg.col = "#EEEEEE")

circos.track(ylim = c(0, 1))
circos.clear()

#### genome plot
circos.par$track.margin = rep(0, 2)
circos.par$cell.padding = rep(0, 4)

circos.initializeWithIdeogram(plotType = NULL)
bed = generateRandomBed(50)
text = sapply(
    letters[sample(26, nrow(bed), replace = TRUE)], 
    function(x) strrep(x, sample(4:6, 1))
)
bed$text = text

circos.stackedText(bed[, 1], bed[, 2], bed$text, cex = 0.7)
circos.genomicIdeogram()
circos.clear()
