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.
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()Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
