You can use circos.info to find out index for all sectors and all tracks.
The function calls draw.sector.
sectors = letters[1:8]
circos.initialize(sectors, xlim = c(0, 1))
for(i in 1:4) {
circos.trackPlotRegion(ylim = c(0, 1))
}
circos.info(plot = TRUE)
highlight.sector(c("a", "h"), track.index = 1)
highlight.sector("c", col = "#00FF0040")
highlight.sector("d", col = NA, border = "red", lwd = 2)
highlight.sector("e", col = "#0000FF40", track.index = c(2, 3))
highlight.sector(c("f", "g"), col = NA, border = "green",
lwd = 2, track.index = c(2, 3))
highlight.sector(sectors, col = "#FFFF0040", track.index = 4)
