circos.barplot(value, pos, bar_width = 0.6,
col = NA, border = "black", lwd = par("lwd"), lty = par("lty"),
sector.index = get.current.sector.index(),
track.index = get.current.track.index())value |
A numeric vector or a matrix. If it is a matrix, columns correspond to the height of bars. |
pos |
Positions of the bars. |
bar_width |
Width of bars. It assumes the bars locating at |
col |
Filled color of bars. |
border |
Color for the border. |
lwd |
Line width. |
lty |
Line style. |
sector.index |
Index of sector. |
track.index |
Index of track. |
If the input variable is a matrix, it draws a stacked barplot.
Please note, the x-values of barplots are normally integer indices. Just be careful when initializing the circular layout.
