Displaying the numbers in an R correlation matrix diagonally
I am generating a correlation matrix using
library(psych)
corMat = cor(data)
cor.plot(corMat,numbers=TRUE,colors=TRUE,n=51,main=NULL,labels=NULL)
but want to alter it so that the numbers displayed inside the heatmap are displayed diagonally.
Solution
I may have misunderstood but if you just want the text labels rotated, you can do so by changing the source of cor.plot, specifically the line text(rx, ry, round(r * 100)) to text(rx, ry, round(r * 100), srt=45), giving something like this:
