I've generated correlation heatmaps using the following code:
corrplot(data, method = "color", type = "lower", order = "hclust", col=colorRampPalette(c("blue","white","red"))(400), tl.col = 'black', cl.ratio = 0.2, tl.srt = 45)
I also have hierarchical clustering results from pvclust and would like to add those results to the correlation plot so that each cluster is grouped together by a box on the correlation plot. Does anyone know how to do this? Thanks!!
