I have a simple 8 by 8 matrix
M <- matrix(rnorm(64), nrow=8, ncol=8)
How should I transform it to plot it with library(corrplot)
? Without transformation the error is:
corrplot.mixed(M)
Error in corrplot(corr, type = "upper", method = upper, diag = TRUE, tl.pos = tl.pos, : The matrix is not in [-1, 1]! which I guess would assume that the matrix should be [-1, 1]?
