R用聚类绘制热图，但隐藏树状图 [英] R draw heatmap with clusters, but hide dendrogram

问题描述

默认情况下，R的 heatmap 将群集行和列:

By default, R's heatmap will cluster rows and columns:

mtscaled = as.matrix(scale(mtcars))
heatmap(mtscaled, scale='none')

我可以禁用群集:

heatmap(mtscaled, Colv=NA, Rowv=NA, scale='none')

然后树状图消失:

但是现在数据不再聚类了.

But now the data is not clustered anymore.

我不希望显示树状图，但是我仍然希望对行和/或列进行聚类.我该怎么办?

I don't want the dendrograms to be shown, but I still want the rows and/or columns to be clustered. How can I do this?

我想要的示例:

推荐答案

library(gplots)
heatmap.2(mtscaled,dendrogram='none', Rowv=TRUE, Colv=TRUE,trace='none')

Rowv -is为TRUE，表示树状图是根据行均值进行计算和重新排序的.

Rowv -is TRUE, which implies dendrogram is computed and reordered based on row means.

Colv -列应与行相同.
