creating a symmetric matrix
Dear R People:
Suppose I have the following:
x <- 1:4
And I want to create the following matrix:
1 2 3 4
2 1 2 3
3 2 1 2
4 3 2 1
Is there a function in place for this, please? I looked at symMatrix
in micEcon and some of the items in Matrix, but they didn't quite do
it.
I can put together something quickly, of course, but it seems likely
that this would exist.
Thanks,
Erin
