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
