Description

This function plots scatter points or broken lines on the river chart.

Usage

RiverPoint(site, river, distance, value, riverlayout, range = NA,
  type = "l", pt.col = "grey40", pt.bg = "black", pt.pch = 20,
  pt.cex = 1, lbl.cex = 0.7, lbl.adj = c(0.5, 2), lbl.ofs = 0.5,
  lbl.col = "black", lbl.srt = 0, lbl.pos = NULL, lbl.shw = FALSE,
  ln.lwd = 1)

Arguments

site	a vector of site IDs.
river	a vector of river names.
distance	a vector of distances from sites to the river mouth.
value	a vector of values.
riverlayout	the output list of RiverLayout or RiverMap.
range	point value range. A vector of two values indicating lower limit and upper limit.
type	type of plot. See plot for details. The default value is "l", which means "lines".
pt.col	point or point border colour.
pt.bg	point point background(fill) colour when pt.pch=21:25.

pt.cex	point size.
lbl.cex	label size.
lbl.adj	label adjustment. One or two values in [0,1] for x and y (optional) adjustment.
lbl.ofs	label position offset.
lbl.col	label colour.
lbl.srt	label angle.
lbl.pos	label position. 1 for below, 2 for left, 3 for above, and 4 for right. See par for details.
