R将corrplot返回为对象

问题描述

corrplot绘制一个相关矩阵，但不返回图形对象(毛刺)

corrplot plots a correlation matrix, but it does not return a graphical object (grob)

我想在单个页面上绘制几个相关矩阵.对于普通图，我将使用gridExtra包中的grid.arrange.但是，由于corrplot仅打印而不返回对象，因此我看不到该怎么做.

I would like to plot several correlation matrices on a single page. For normal plots, I would use grid.arrange from the gridExtra package. However since corrplot only prints and does not return an object, I can't see how to do this.

是否有替代方法或更好的替代方法corrplot?

Is there a workaround or a better alternative to corrplot ?

推荐答案

有一个旧的备用数据库par(mfrow=c(x, y))，其中x是要绘制的行数，而y是列数.然后，它在您调用绘图时跨过然后向下发布.

There's the old standby par(mfrow=c(x, y)) where x is the number of rows you wish to plot and y the numberof columns. It then posts across and then down as you call the plots.

par(mfrow = c(2, 2))
corrplot(cor(mat1))
corrplot(cor(mat2))
corrplot(cor(mat3))
corrplot(cor(mat4))

par(mfrow = c(1, 1)) #To clear layout

将情节绘制为

Mat1 | Mat2
-----------
Mat3 | Mat4
