RiverReach: River Reach Plotting

In rivervis: River Visualisation Tool

Description

This highlights river reaches on the river chart.

Usage

RiverReach(reach, river, from, to, group, style, riverlayout, rea.pos = NA,
  rea.col = "lightblue", rea.lty = 1, rea.lwd = 1, rea.den = NULL,
  bd.col = "black", ln.shw = T, ln.col = "grey40", ln.lty = 3,
  ln.lwd = 1, pt.shw = T, pt.col = "black", pt.pch = 20,
  pt.bg = "black", pt.cex = 1, pt.lwd = 1)

Arguments

reach	a vector of reach names.
river	a vector of rivers to which the reaches belong.
from	a numeric vector of starting points.
to	a numeric vector of ending points.
group	a vector of reach group names. This indicates to which group the reaches belong.
style	a vector of reach styles. The value of "style" denotes the location of reach lines. Especially, 0 denotes "on axis" and 99 means "the reach is presented as a band rather than a line".
riverlayout	the output list of RiverLayout or RiverMap.
rea.pos	a vector of absolute positions of lines. The values range in [0,1].
rea.col	line colour.
rea.lty	line style.
rea.lwd	line width.
rea.den	the density of shading lines, in lines per inch. See rect.
bd.col	colour of river chart frames.
ln.shw	show lead lines (TRUE) or not (FALSE).
ln.col	lead line colour.
ln.lty	lead line style.
ln.lwd	lead line width.
pt.shw	show anchor point (TRUE) or not (FALSE). Anchor points represent the locations of the river mouths.
pt.col	anchor point colour.
pt.pch	anchor point style.
pt.bg	anchor point background(fill) colour when pch=21:25.
pt.cex	anchor point size.
pt.lwd	anchor point border width.
