Adds a new column normalized_weight to a trophic_tbl object so that,
for each target node (to), the sum of incoming weights equals 1.
Arguments
- tbl
A trophic_tbl object.
Value
A trophic_tbl object with an additional column
normalized_weight.
Details
For every unique value in the to elements of the link column,
the function divides each corresponding weight by the total weight of all links
pointing to that same node.
Nodes with no incoming links are left unchanged.
Examples
net <- trophic() |>
add_link("a", "b", weight = 2) |>
add_link("c", "b", weight = 3)
net_norm <- normalize_weights(net)
