ReExpNetwork: ReExpress stream networks indexed network traversal.

In mccreigh/rwrfhydro: R tools for the WRF Hydro Model

Description

ReExpNetwork re-expresses topological relationships between three variables, [from, to, id] (as used by NHD+v2.1) into separate lists for index based up- and down- stream traversal, depending on the upstream argument.

Usage

ReExpNetwork(routeLinkReInd, upstream = TRUE, parallel = FALSE)

Arguments

routeLinkReInd	The netcdf routelink file to process.
upstream	Logical, re-express connectivity upstream (TRUE) or downstream (FALSE).
parallel	Logical use a registered backend for plyr?

Value

The resulting file which was written to disk, of the form the "infile.reExpTo.nc" (downstream) or "infile.reExpFrom.nc" (upstream).
