In rivervis: River Visualisation Tool

Description

This plots bars for quantitative data on the river chart.

Usage

RiverBar(site, river, distance, value, riverlayout, range = NA, bar.w = 1,
  bar.col = NA, bd.col = "black", 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 = TRUE, pt.shw = FALSE)

Arguments

site	a character vector of site names.
river	a vector of rivers on which the sites are located.
distance	a vector. The along-the-river distances between the sites and the mouth of the river.
value	a data frame containing the variables to be shown on the bar-chart.
riverlayout	the output list of RiverLayout or RiverMap.
range	bar-chart value range. A vector of two values indicating lower limit and upper limit.
bar.w	relative width of each bar plotted in the diagram. The default value is 1.
bar.col	bar colour.
bd.col	bar border colour.
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.
lbl.shw	show labels (TRUE) or not (FALSE).
pt.shw	show location point (TRUE) or not (FALSE).

riverlayout <- RiverLayout(B.river$River,B.river$Length,
                           B.river$Parent,B.river$Position,
                           B.river$Distance, direction = -1)

RiverDraw(riverlayout)

RiverBar(B.siteaspt$Site, B.siteaspt$River, B.siteaspt$Distance,
         B.siteaspt[4], riverlayout, range = c(0,8),
         bar.col = c("#5381FFFF"), lbl.adj = c(0.5,1.3))

RiverDraw(riverlayout)

RiverBar(B.siteaspt$Site, B.siteaspt$River, B.siteaspt$Distance,

         bar.col = c("#5381FFFF", "#FF3931FF"), lbl.adj = c(0.5,1.3))
