How to make clusters in heat map using ggplot2?

Question

[John]

Hey there,

How can I cluster the heat map using ggplot2? I know already ggplot2 doesn't contain clustering, but is there any way to do that?

and which is the best and easy package to plot heatmap in R? (should have color key, clustering)

I used heatmap2 with good outcomes. I think this is the actual tutorial I used:
