Upper Triangular Vector to Matrix

Returns the symmatric square matrix from a vector containing the upper triangular elements

UT2mat(x, diag = 0, LT = 0)

`x`	A vector containing the upper triangular elements of a square, symmetric matrix.
`diag`	A scalar value to use for the diagonal values of the matrix, or `"x"` if `x` includes the diagonal values. Default: `NA`.
`LT`	A scalar value to use for the lower triangular values of the matrix. Default: `0`.

A symmetric matrix with the values of x in the upper and lower triangles and the value diag on the diagonal.
