ccGenomicAxis: Add genomic axes

In circlizePlus: Using 'ggplot2' Feature to Write Readable R Code for Circular Visualization

Add genomic axes

Description

Object ccGenomicCellGeom will call the function circlize::circos.genomicAxis while drawing.

Usage

ccGenomicAxis(
  h = "top",
  major.at = NULL,
  labels = NULL,
  major.by = NULL,
  tickLabelsStartFromZero = TRUE,
  labels.cex = 0.4 * par("cex"),
  ...
)

Arguments

h	Position of the axes. "top" or "bottom".
major.at	Major breaks. If major.at is set, major.by is ignored.
labels	labels corresponding to major.at. If labels is set, major.at must be set.
major.by	Increment of major ticks. It is calculated automatically if the value is not set (about every 10 degrees there is a major tick).
tickLabelsStartFromZero	Whether axis tick labels start from 0? This will only affect the axis labels while not affect x-values in cells.
labels.cex	The font size for the axis tick labels.
...	Other arguments pass to circos.axis.

Value

Object ccGenomicCellGeom

Examples

library(circlizePlus)
cc <- ccPlot(initMode = "initializeWithIdeogram",
chromosome.index = paste0("chr", 1:4), plotType = NULL)
track <- ccTrack(ylim = c(0, 1))
cell <- ccCell(sector.index = "chr1") + ccGenomicAxis()
e <- track + cell
cc + e
