In nhdplusTools: NHDPlus Tools

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)

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?

Value

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

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)
