Dear all
Is there an easy way to display only one half (top-right or
bottom-left) of a correlation matrix?
require(Hmisc)
rcorr(as.matrix(mtcars[ , 1:4]))
mpg cyl disphp
mpg 1.00 -0.85 -0.85 -0.78
cyl -0.85 1.00 0.90 0.83
disp -0.85 0.90 1.00 0.79
hp -0.78 0.83 0.79

Seems promising, but for one issue: I would like to keep the diagonal
and thus specify 'diag=T', but then as.dist() replaces the diagonal
values with zero. (See below.) Is there a

if as.dist doesn't work, use brute force:
x = matrix(rnorm(5*100), 100, 5)
mat = signif(cor(x), 2);
mat[lower.tri(mat)] =
data.frame(mat)
Yes, brute force works. This isn't quite how I wanted to do this,
