Functions for drawing gapped cluster heatmap with ggplot2
Ryo Sakai ryo.sakai@esat.kuleuven.be
This is a set of tools for drawing gapmaps using ggplot
gap_data
extracts data from a dendrogram object. Make sure to convert hclust
object to dendrogram
object by calling as.dendrogram()
.
This method generates an object class gapdata
, consisting of a list of data.frames
.
The general workflow is as following:
Hierarchical clustering hclust()
Convert the hclust
output class into dendrogram
by calling as.dendrogram()
Generate a gapped cluster heatmap by specifying a matrix
and dendrogram
objects for rows and columns in gapmap()
