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"))

`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

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.

Gu, Z. (2014) circlize implements and enhances circular visualization in R. Bioinformatics.

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()
