symet: Symmetrization and diagonal loading of a transition matrix

In sequence: Analysis of Sequences of Events

Description

Adds the matrix to its transpose (X + t(X)) and loads its diagonal by the sum of each row.

Usage

symet(x, sym = TRUE, charge = TRUE, ident = FALSE)

Arguments

x	data.frame: The matrix to process as a data.frame
sym	logical: symmetrisation.
charge	logical: diagonal loading.
ident	logical: first column consists in identifiers.

Value

a data.frame: the resulting matrix
