Make a matrix symmetric
Description
This function was part of the package ENA. This package is no more available
and it cannot be installed from archive because some dependencies are no more
available.
Usage
symmetricize(
matrix,
method = c("max", "min", "avg", "ld", "ud"),
adjacencyList = FALSE
)
Arguments
matrix |
The matrix to make symmetric |
method |
The method to use to make the matrix symmetric. Default is to take the maximum.
|
adjacencyList |
Logical. If false, returns the symmetric matrix (the same format as the input). If true, returns an adjacency list representing the upper triangular portion of the adjacency matrix with addressing based on the row.names of the matrix provided. |
Details
Make the matrix symmetric by making all "mirrored" positions consistent. A variety of methods are provided to make the matrix symmetrical.
Value
The symmetric matrix

Examples
#Create a sample 3x3 matrix
mat <- matrix(1:9, ncol=3)
#Copy the upper diagonal portion to the lower
symmetricize(mat, "ud")
#Take the average of each symmetric location
symmetricize(mat, "avg")
