R中pheatmap中的x轴和y轴标签

I really like how the pheatmap package creates very nice looking heatmaps in R. However, I am trying to add x and y axis labels to the output (if one were just in plot(), one would use: xlab = 'stuff'). A simple example is as follows.

我真的很喜欢pheatmap包在R中创建非常好看的热图。但是，我试图在输出中添加x和y轴标签（如果只是在plot（）中，可以使用：xlab ='stuff'） 。一个简单的例子如下。

require(pheatmap)

## Generate some data
d <- matrix(rnorm(25), 5, 5)
colnames(d) = paste("bip", 1:5, sep = "")
rownames(d) = paste("blob", 1:5, sep = "")

## Create the heatmap:
pheatmap(d)

The above yields the following heatmap:

以上产生以下热图：

I cannot for the life of me figure out how to add an 'xlab' or 'ylab' to this plot. Thoughts?

我不能为我的生活弄清楚如何在这个情节中添加'xlab'或'ylab'。思考？

The main issue here is that pheatmap, which uses grid package, creates a new grid page each time it is called. The solution I've found is:

这里的主要问题是使用网格包的pheatmap每次调用时都会创建一个新的网格页面。我发现的解决方案是：

library(pheatmap)
library(grid)

## Generate some data
d <- matrix(rnorm(25), 5, 5)
colnames(d) = paste("bip", 1:5, sep = "")
rownames(d) = paste("blob", 1:5, sep = "")

## Create the heatmap:
setHook("grid.newpage", function() pushViewport(viewport(x=1,y=1,width=0.9, height=0.9, name="vp", just=c("right","top"))), action="prepend")
pheatmap(d)
setHook("grid.newpage", NULL, "replace")
grid.text("xlabel example", y=-0.07, gp=gpar(fontsize=16))
grid.text("ylabel example", x=-0.07, rot=90, gp=gpar(fontsize=16))
