nhdplusTools (version 1.3.2)

get_path_members: Get Path Members (DEPRECATED)

Description

Given a network and set of IDs, finds paths between all identified flowpath outlets. This algorithm finds members between outlets regardless of flow direction.

Usage

get_path_members(outlets, network, cores = 1, status = FALSE)

Value

list of lists containing flowpath identifiers along path that connect outlets.

Arguments

outlets

vector of IDs from data.frame

network

data.frame with ID, toID, and lengthkm attributes.

cores

integer number of cores to use for parallel computation.

status

logical print status and progress bars?

Examples

source(system.file("extdata", "walker_data.R", package = "nhdplusTools"))
fline <- walker_flowline

outlets <- c(5329303, 5329357, 5329317, 5329365, 5329435, 5329817)

# Add toCOMID
fline <- nhdplusTools::get_tocomid(fline, add = TRUE)

fl <- dplyr::select(fline, ID = comid, toID = tocomid, lengthkm)

get_path_members(outlets, fl)
