An object of class matrix

order

Details

The matrix mat must be symmetric and have rows and columns names. Its values are not modified.

Examples

mat <- matrix(rnorm(36), 6)
mat[lower.tri(mat)] <- t(mat)[lower.tri(mat)]
row.names(mat) <- colnames(mat) <- c("A", "C", "E", "B", "D", "F")
order <- c("A", "B", "C", "D", "E", "F")
mat <- reorder_mat(mat = mat, order = order)
