Add labels to specified genomic regions

circos.genomicLabels(bed, labels = NULL, labels.column = NULL,
    col = par("col"), cex = 0.8, font = par("font"), padding = 0.4,
    connection_height = convert_height(5, "mm"),
    line_col = par("col"), line_lwd = par("lwd"), line_lty = par("lty"),
    labels_height = min(c(convert_height(1.5, "cm"),
    max(strwidth(labels, cex = cex, font = font)))),
    side = c("inside", "outside"), track.margin = circos.par("track.margin"))

`bed`	a data frame in bed format
`labels`	a vector of labels corresponding to rows in `bed`
`labels.column`	if the label column is already in `bed`, the index for this column in `bed`
`col`	color for the labels
`cex`	size of the labels
`font`	font of the labels
`padding`	padding of the labels, the value is the ratio to the height of the label
`connection_height`	height of the connection track
`line_col`	color for the connection lines
`line_lwd`	line width for the connection lines
`line_lty`	line type for the connectioin lines
`labels_height`	height of the labels track
`side`	side of the labels track, is it in the inside of the track where the regions are marked?
`track.margin`	bottom and top margins

The function adds labels for the specified regions. The positions of labels are arranged so that they are not overlapping to each other.
