R中的热图如何调整列标签的大小? [英] heatmap in R how to resize columns labels?

问题描述

我有一个约4000行100列的data.matrix.我正在对数据进行热图绘制，例如:

I have a data.matrix that is approximately 4000 rows and 100 columns. I am doing a heatmap of the data like:

data<-heatmap(data_matrix,Rowv=NA,Colv=NA,col=cm.colors(256),scale="column",margins=c(5,10))

但是我得到的问题是，列中出现的标签过于分组，因此无法正确地可视化它们.如何调整热图的大小，以便可以看到列标签的值?我尝试将其打印为pdf，但它仅显示黑色条纹.谢谢

But the problem that I got is that the labels that appear in the column are too grouped, so it is impossible to visualize them correctly. How I can resize the heatmap so I can see the values of the labels of the column? I tried to print it in pdf, but it only appears a black stripe. Thanks

我包括一个热图图，我想看的部分是标签在右边的部分，但它们太靠近了.

I am including a figure of the heatmap, the portion that I want to see are the labels that are in the right part, but they are too close together.

推荐答案

在Rstudio中，您可以轻松调整图形窗口的大小，这与Rgui相同.另外，如果您将图解保存到文件中，则可以为图形使用更大的尺寸，例如调用 pdf 或 png 时，较大的 width 和 height .

In Rstudio you can easily resize the graphic window, same holds for Rgui. Alternatively, if you save the plot to file you can use a bigger size for your graphics, e.g. bigger width and height when calling pdf or png.
