Draw a link between two matrix rows in the circular heatmap

Object ccHeatmapLink will call the function circlize::circos.heatmap.link while drawing.

Usage

ccHeatmapLink(row_from, row_to, ...)

Arguments

row_from

The row index where the link starts. The value should be length 1. If you want to draw multiple links, put the function in a for loop.

row_to

The row index where the link ends.

...

Pass to circos.link.

Value

Object ccHeatmapLink

Examples

library(circlizePlus)
set.seed(123)
mat = matrix(rnorm(100*10), nrow = 100)
rownames(mat) = paste0("R", 1:100)
col_fun = colorRamp2(c(-2, 0, 2), c("blue", "white", "red"))
cc = ccHeatmap(mat, col = col_fun, rownames.side = "outside")
link1 = ccHeatmapLink(10, 60)
cc + link1
