Creates a data frame showing the path (through various detection sites) to reach each detection location in a parent-child table.
buildPaths(parent_child = NULL, direction = c("u", "d"))data frame with at least `parent` and `child` columns. Can be created with `buildParentChild()` function.
the direction of movement. Parent-child tables are generally built imagining parents as downstream from children. Assuming that's the case, should the paths be upstream (`u` or `upstream`), the default, or downstream (`d` or `downstream`)?
data frame containing a column,`end_loc`, showing the possible final locations, and a column, `path`, showing all the detection locations to pass on the way to that final location.
