From flows v1.1.1
by Timothe Giraud
Comparison of Two Matrices
Compares two matrices of same dimension, with same column and row names.
Usage
compmat(mat1, mat2, digits = 0)
Arguments
 mat1
 A square matrix of flows.
 mat2
 A square matrix of flows.
 digits
 An integer indicating the number of decimal places to be used when printing the data.frame in the console (see round).
Value

A data.frame that provides statistics on differences
between mat1 and mat2: absdiff are the
absolute differences and reldiff are the relative differences (in percent).

Examples
# Import data
data(nav)
myflows < prepflows(mat = nav, i = "i", j = "j", fij = "fij")
# Remove the matrix diagonal
diag(myflows) < 0
# Select the dominant flows (incoming flows criterion)
flowSel1 < domflows(mat = myflows, w = colSums(myflows), k = 1)
# Select the first flows
flowSel2 < firstflows(mat = myflows, method = "nfirst", ties.method = "first",
k = 1)
# Select flows greater than 2000
flowSel3 < firstflows(mat = myflows, method = "xfirst", k = 2000)
# Combine selections
flowSel < myflows * flowSel1 * flowSel2 * flowSel3
# Compare flow matrices
compmat(mat1 = myflows, mat2 = flowSel, digits = 1)
