Compares two matrices of same dimension, with same column and row names.
1 | compmat(mat1, mat2, digits = 0)
|
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). |
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).

# Select flows greater than 2000
flowSel3 <- firstflows(mat = myflows, method = "xfirst", k = 2000)
# Combine selections
flowSel <- myflows * flowSel1 * flowSel2 * flowSel3
# Compare flow matrices
