check_transitivity: Check transitivity of station matrix
In ECCC-MSC/Basin-Delineation: Finds upstream area and upstream stations
Description
Usage
Arguments
Details
Value
Description
Finds all monitoring stations that violate the assumption
of transitivity for upstream/downstream relations.
Usage
1
Arguments
table
a data table created from initialize_matrix_from_stations. An
(n x n+1) data.table with first column named "ID" and all other columns
named according to station number. Row i and column i+1 should correspond to
the same station.
Details
The transitivity assumption states that if x is upstream of y and
y is upstream of z, then x is upstream of z. This tests that assumption for a
matrix
Value
A list with an element for every x,y station pair that violates
the transitivity assumption or an empty vector
