I found this topic and I would like to got similar result plot. I am trying to plot a heatmap with the library pheatmap in R and I need to increase the left branch size. I would like to decrease the colored area and increase dendrogram branches. I found another topic that do a bit of what I need, but in that one, dendrogram is splitted from heatmap. Here is a sample code:
library(pheatmap)
test = cbind(matrix(rnorm(3000), 100, 2), matrix(rnorm(3000)+10, 100, 2))
pheatmap(test)
pheatmap(test, cluster_cols = FALSE)
