circos_link: A modified circos plot from OmicCircos package
In lpwgit/contPredict: contPredict R Package

To draw circular plot with links shows contamination paired samples

`mapping`	data frame, circos plot data
`xc`	integer, circle center x coordinate
`yc`	integer, circle center y coordinate
`R`	interger, circle radius
`W`	interger, circle width
`cir`	data frame, circle circumference
`type`	character, plot type [chr\|link]
`print.chr.lab`	logical, TRUE: print chr label, FALSE: not print chr label
`cex`	numeric, plot font size
`lwd`	interger, line width
`col`	vector, colors
`side`	character, segment label position [in\|out]
`scale`	logic, scale the circos size (default: FALSE)
`seg.lab.size`	numeric, segment label font size (default: 1)
`link.wd`	numeric, link width (default: 1)
`lower_arch`	numeric, (default: 1)
`line_type`	character, line type (default: "l")
