Highlight sectors and tracks

Highlight sectors and tracks

highlight.sector(
    sector.index,
    track.index = get.all.track.index(),
    col = "#FF000040",
    border = NA,
    lwd = par("lwd"),
    lty = par("lty"),
    padding = c(0, 0, 0, 0),
    text = NULL,
    text.col = par("col"),
    text.vjust = 0.5,
    ...)

Arguments

sector.index	A vector of sector index
track.index	A vector of track index that you want to highlight
col	Color for highlighting. Note the color should be semi-transparent.
border	Border of the highlighted region
lwd	Width of borders
lty	Style of borders
padding	Padding for the highlighted region. It should contain four values representing ratios of the width or height of the highlighted region
text	text added in the highlight region, only support plotting one string at a time
text.vjust	adjustment on 'vertical' (radical) direction. Besides to set it as numeric values, the value can also be a string contain absoute unit, e.g. "2.1mm", "-1 inche", but only "mm", "cm", "inches"/"inche" are allowed.

Examples

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)
