calculateChannelMetrics: Calculate channel metrics

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

Description

Calculate the channel metrics: xbkf_w, sdbkf_w, n_bw, xinc_h, sdinc_h, n_incis, xbkf_h, sdbkf_h, n_bh.

Usage

calculateChannelMetrics(uid, bankwid, incishgt, bankhgt)

Arguments

uid	a vector of site identifiers
bankwid	a vector of bankfull width measurements; sum of extra transect pairs
incishgt	a vector of incision heights; max of extra transect pairs
bankhgt	a vector of bankfull heights; max of extra transect pairs

Details

The EPA uses data where the extra transect - transect pairs have been joined. The bankwid argument is the sum of the extra transect pairs, the incishgt and bankhgt arguments are the max of the extra transect pairs. These can be calculated using joinExtraTransects.

Examples

d <- data.frame(uid = rep(1:10, 11), bankwid = runif(110), incishgt = runif(110), bankhgt = runif(110))
calculateChannelMetrics(d$uid, d$wetwid, d$bankwid, d$incishgt, d$bankhgt)
