calculateLWDCumulativeMetrics: Calculate cumulative LWD metrics

In jasonelaw/nrsa: Calculate metrics for NRSA protocol data.

Description

This function calculates count and volume metrics by size class.

Usage

calculateLWDCumulativeMetrics(uid, size.class, count, is.wadeable, lwdlength,
  lwdarea, epa.names = T)

Arguments

uid	vector of site-visit indicators
size.class	A vector of size class codes (e.g., WSDSL, DXDLL, ...)
count	vector of counts of LWD pieces
is.wadeable	logical describing whether the site is wadeable or not
lwdlength	numeric, the total stream length over which LWD has been quantified at the site.
lwdarea	numeric, the total area over which LWD has been quantified at the site.
epa.names	should the metrics be in data.frame format with EPA's names or in contingency table style. Defaults to EPA style.

Details

The lwdlength and lwdarea argument should be as calculated by calculateLWDSiteLength and calculateLWDSiteArea functions, respectively.

Value

If the epa.names argument is FALSE, then the function returns an array of cumulative counts within size classes. If TRUE, the function returns a metric data.frame with epa metric names.
