Automatically generate alter_fun

Description

Automatically generate alter_fun

Usage

alter_graphic(graphic = c("rect", "point"),
    width = 1, height = 1,
    horiz_margin = unit(1, "pt"), vertical_margin = unit(1, "pt"),
    fill = "red", col = NA, pch = 16, ...)

Arguments

graphic	Graphic to draw.
width	Relative width of the rectangle.
height	Relative height of the rectangle.
horiz_margin	Horizontal margin. E.g. if you want 1mm margin on top and 1mm margin at bottom of the rectangle, set this value to unit(1, 'mm').
vertical_margin	Vertical margin.
fill	Filled color.
col	Border color.
pch	Pch for points
...	Pass to gpar

Details

This function aims to simplify the definition of functions in alter_fun. Now it only supports rectangles and points.

Examples

mat = read.table(textConnection(
"s1,s2,s3
g1,snv;indel,snv,indel
g2,,snv;indel,snv
g3,snv,,indel;snv"), row.names = 1, header = TRUE, sep = ",", stringsAsFactors = FALSE)
mat = as.matrix(mat)
col = c(snv = "red", indel = "blue")

oncoPrint(mat, 
	alter_fun = list(
		snv = alter_graphic("rect", width = 0.9, height = 0.9, fill = col["snv"]),
		indel = alter_graphic("rect", width = 0.9, height = 0.9, fill = col["indel"])
	), col = col)
