Update the plotting region in an existed cell

Update the plotting region in an existed cell

circos.updatePlotRegion(
    sector.index = get.cell.meta.data("sector.index"),
    track.index = get.cell.meta.data("track.index"),
    bg.col = NA,
    bg.border = "black",
    bg.lty = par("lty"),
    bg.lwd = par("lwd"))

Arguments

sector.index	Index for the sector
track.index	Index for the track
bg.col	Background color for the plotting region
bg.border	Color for the border of the plotting region
bg.lty	Line style for the border of the plotting region
bg.lwd	Line width for the border of the plotting region

Details

You can update an existed cell by this function by erasing all the graphics. But the xlim and ylim inside the cell still remain unchanged.

Note if you use circos.track to update an already created track, you can re-define ylim in these cells.

Examples

circos.initialize(letters[1:8], xlim = c(0, 1))
circos.track(ylim = c(0, 1), panel.fun = function(x, y) {
    circos.text(CELL_META$xcenter, CELL_META$ycenter, CELL_META$sector.index)
})
circos.update(sector.index = "b", track.index = 1)
circos.rect(CELL_META$cell.xlim[1], CELL_META$cell.ylim[1],
            CELL_META$cell.xlim[2], CELL_META$cell.ylim[2],
            col = "#FF000080")
circos.clear()
