prune.rivernet

Prune a river network at specified reaches.

Functions for reading, analysing and plotting river networks.
For this package, river networks consist of sections and nodes with associated attributes,
e.g. to characterise their morphological, chemical and biological state.
The package provides functions to read this data from text files, to analyse the network
structure and network paths and regions consisting of sections and nodes that fulfill
prescribed criteria, and to plot the river network and associated properties.

prune.rivernet function

<dl> <dt>net</dt>
<dd>Object of class "rivernet" e.g. read by the function <code>rivernet.read</code>.</dd> <dt>reach.up</dt>
<dd>Numerical vector of reach indices from which to prune all upstream reaches (the indicated reaches to prune from will be kept in the pruned network). Note that you can get reach indices from coordinates with the function <code>getreachind.rivernet</code>.</dd> <dt>reach.dn</dt>
<dd>Numerical vector of reach indices from which to prune all downstream reaches and branches from downstream reaches (the indicated reaches to prune from will be kept in the pruned network). Note that you can get reach indices from coordinates with the function <code>getreachind.rivernet</code>.</dd> <dt>verbose</dt>
<dd>Logical argument to specify whether there should be (minimal) output over what has been done.</dd></dl>
