Circular visualization in R
This package aims to implement circular layout in R.
Since most of the figures are composed of points, lines and polygons, we just need to implement low-level functions for drawing points, lines and polygons.
Current there are following low-level graphic functions:
circos.points
circos.lines
circos.rect
circos.polygon
circos.segments
circos.text
circos.axis, circos.xaxis, circos.yaxis
circos.barplot
circos.boxplot
circos.violin
circos.link
For drawing points, lines and text through the whole track (among several sectors), the following functions are available:
circos.trackPoints
circos.trackLines
circos.trackText
Draw circular heatmaps
circos.heatmap
Functions to arrange circular layout:
circos.initialize
circos.track
circos.nested
circos.update
circos.par
circos.info
circos.clear
Theoretically, you are able to draw most kinds of circular plots by the above functions.
For specific use in genomics, we also implement functions which add graphics in genome scale.
Functions to initialize circos plot with genomic coordinates:
circos.initializeWithIdeogram
circos.genomicInitialize
Functions to arrange genomic circular layout:
circos.genomicTrack
Functions to add basic graphics in genomic scale:
circos.genomicPoints
circos.genomicLines
circos.genomicText
circos.genomicRect
circos.genomicLink
Functions with specific purpose:
circos.genomicDensity
circos.genomicRainfall
circos.genomicIdeogram
circos.genomicHeatmap
circos.genomicLabels
Finally, function that draws Chord diagram:
chordDiagram
Please refer to the vignettes (https://jokergoo.github.io/circlize_book/book/ ) to find out how to draw basic and advanced circular plots by this package.
