Test alter_fun for oncoPrint()

Test alter_fun for oncoPrint()

test_alter_fun(fun, type, asp_ratio = 1)

Arguments

fun	The alter_fun for oncoPrint. The value can be a list of functions or a single function. See https://jokergoo.github.io/ComplexHeatmap-reference/book/oncoprint.html#define-the-alter-fun
type	A vector of alteration types. It is only used when fun is a single function.
asp_ratio	The aspect ratio (width/height) for the small rectangles.

Details

This function helps you to have a quick view of how the graphics for each alteration type and combinations look like.

Examples

alter_fun = list(
        mut1 = function(x, y, w, h) grid.rect(x, y, w, h, gp = gpar(fill = "red", col = NA)),
        mut2 = function(x, y, w, h) grid.rect(x, y, w, h, gp = gpar(fill = "blue", col = NA)),
        mut3 = function(x, y, w, h) grid.rect(x, y, w, h, gp = gpar(fill = "yellow", col = NA)),
        mut4 = function(x, y, w, h) grid.rect(x, y, w, h, gp = gpar(fill = "purple", col = NA)),
        mut5 = function(x, y, w, h) grid.rect(x, y, w, h, gp = gpar(lwd = 2)),
        mut6 = function(x, y, w, h) grid.points(x, y, pch = 16),
        mut7 = function(x, y, w, h) grid.segments(x - w*0.5, y - h*0.5, x + w*0.5, y + h*0.5, gp = gpar(lwd = 2))
