如何包含来自不同矩阵的p-vlaues并更改corrplot中的圆形/正方形大小？

Question

Users,

I have two matrices "mm" and "mpm" of same size. The "mm" matrix contains pre-computed spearman's-rho correlation values and the "mpm" matrix contains the p-value corresponding to the correlation values.

> mm[1:5,1:5]

I want the p-values from the "mpm" to be plotted on the cells. And when I use the following code:

> corrplot(mm, is.corr = FALSE, method = "circle", p.mat = mpm[[1]], insig = "p-value", sig.level=-1)

I get this this error:

Error in ind[, 2] : incorrect number of dimensions

Can anyone help me with this ? Also, is it possible to alter the size of the cells based on p-values ? Thanks in advance for any help.

Answer 1

You need to convert mm and mpm to matrix .

library(corrplot)
corrplot(as.matrix(mm), is.corr = FALSE, method = "circle", 
         p.mat = as.matrix(mpm), insig = "p-value", sig.level=-1)
