Precedence matrix

The precedence matrix shows the flows from one activity to another in a rectangular format. The precedence_matrix() function returns a data frame, which can be visualized in an actual grid using the plot() function.

eventlog %>% precedence_matrix(type = "___") %>% plot()

There are four different types of values:

The overall "absolute" frequency.
The overall "relative" frequency.
The "relative-antecedent" frequency, e.g. A is x% of time followed by B.
The "relative-consequent" frequency, e.g. C is x% of time preceded by D.
