ccGenomicLines: Add lines for genomic data visualization

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

Add lines for genomic data visualization

Description

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

Usage

ccGenomicLines(
  region = NULL,
  value = NULL,
  numeric.column = NULL,
  posTransform = NULL,
  col = ifelse(area, "grey", "black"),
  lwd = par("lwd"),
  lty = par("lty"),
  type = "l",
  area = FALSE,
  area.baseline = NULL,
  border = "black",
  baseline = "bottom",
  pt.col = par("col"),
  cex = par("cex"),
  pch = par("pch"),
  ...
)

Arguments

region	A data frame contains 2 column which correspond to start positions and end positions.
value	A data frame contains values and other information.
numeric.column	Which column in value data frame should be taken as y-value. If it is not defined, the whole numeric columns in value will be taken.
posTransform	Self-defined function to transform genomic positions, see posTransform.default for explaination.
col	col of lines/areas. If there are more than one numeric column, the length of col can be either one or number of numeric columns. If there is only one numeric column and type is either segment or h, the length of col can be either one or number of rows of region. pass to circos.lines
lwd	Settings are similar as col. Pass to circos.lines.
lty	Settings are similar as col. Pass to circos.lines.
type	There is an additional option segment which plot segment lines from start position to end position. Settings are similar as col. Pass to circos.lines.
area	Settings are similar as col. Pass to circos.lines.
area.baseline	Deprecated, use baseline instead.
border	Settings are similar as col. Pass to circos.lines.
baseline	Settings are similar as col. Pass to circos.lines.
pt.col	Settings are similar as col. Pass to circos.lines.
cex	Settings are similar as col. Pass to circos.lines.
pch	Settings are similar as col. Pass to circos.lines.
...	Mysterious parameters.

Examples

library(circlizePlus)
data <- generateRandomBed(nr = 30, nc = 2)
all_chr <- c("chr1", "chr2", "chr3", "chr4", "chr5", "chr6", "chr7", "chr8",
"chr9", "chr10", "chr11", "chr12", "chr13", "chr14", "chr15", "chr16",
"chr17", "chr18", "chr19", "chr20", "chr21", "chr22", "chrX", "chrY")
cc <- ccPlot(initMode = "initializeWithIdeogram", plotType = NULL)
t1 <- ccGenomicTrack(data = data, numeric.column = 4)
cells1 <- ccCells(sector.indexes = all_chr) +
ccGenomicLines(numeric.column = 2)
t1 <- t1 + cells1
show(cc + t1)
