Arguments

units: Vector of unit labels.
relations: Vector of relations.
direction: Are the units in relations "above" or "below" the ones in units?

Value

A data frame of directed edges represented by to and from columns, which can be used as the nodes argument to tidygraph::tbl_graph().

Examples

strat_connect(
  units = c("A", "B", "C"),
  relations = list("B", "C", NA),
  direction = "above"
)
#>   to from
#> 1  A    B
#> 2  B    C
