如何更改 corrplot 的颜色、字体类型和大小？

Question

I find the red font quite abrasive and the size is always too large. What are the parameters to change the font of the variables?

Answer 1

You can use tl.col to change the color, tl.cex to change the size and tl.srt to change the rotation degree. Here is an example:

corrplot(cor(iris[,-5]), tl.col="black", tl.cex=0.8, tl.srt=70)
