The most basic way to do something like this would be using ?image as follows:
做这样的事情最基本的方法是使用？image如下：
M <- matrix(runif(100),10,10)
M[lower.tri(M)] <- NA
image(1:10,1:10,M)
which would result in something like this:
这会产生这样的结果：
You could also investigate the functions ?heatmap or in the gplots package ?heatmap.2. Doing this using ggplot2 using geom_tile is a little different but you can find some examples to walk you through the process here.
您还可以调查函数？heatmap或在gplots包中？heatmap.2。使用gomplot2使用geom_tile执行此操作有点不同，但您可以找到一些示例来指导您完成此过程。
