RiverBlockChart: River Block Chart Plotting

Description

This function plots a river block chart to display qualitative data without the topological structure of the river network. The function does not require the output list from RiverLayout or RiverMap.

Usage

RiverBlockChart(site, river, distance, value, arrangement, h.gap = 0.1, w.gap = 0.25, w.gap.s = 0.1, r.gap = 0.25, block.col = NA, block.lwd = 1, border.col = "grey20", bg.col = "lightgrey", mar = 0.1, hw.rat = 1.5, site.shw = TRUE, site.pos = 1, site.ofs = 1.5, site.cex = 0.5, site.col = "black", site.order = "A", site.srt = 0, rvr.shw = TRUE, rvr.ofs = 1.5, rvr.cex = 0.7, rvr.col = "black", rvr.t.b = "b", rvr.order = NA, rvr.srt = 0, par.shw = TRUE, par.pos = 2, par.ofs = 1, par.cex = 0.6, par.adj = c(1, 0.5), par.col = "black", par.txt = NA)

Arguments

site

a character vector of site names.

river

a vector of rivers to which the sites belong.

distance

a vector. The along-the-river distance between the site and the mouth of the river.

value

a data frame containing the qualitative variables to be shown on the river block-chart.

arrangement

a vector indicating the block number for each line.

h.gap

vertical gap size between blocks in the plot. By default, the vertical gap is block height * 0.1

w.gap

horizontal gap size between sites. By default, the horizontal gap is largest block width * 0.25.

w.gap.s

horizontal gap size between small blocks when there are more than one block in each line. By default, the horizontal gap is largest block width * 0.1.

r.gap

horizontal gap size between rivers. By default, gap between rivers is block width * 0.25.

block.col

a vector of block colours. The length of vector should be as the same as the the number of levels of value.

block.lwd

a value of block line width.

border.col

a value of block border colour.

bg.col

a value of river background colour.

mar

a value of smallest margin size.

hw.rat

the ratio of block height and block width.

site.shw

show site names (TRUE) or not (FALSE).

site.pos

site position. 1 for below, 2 for left, 3 for above, and 4 for right. See par for details.

site.ofs

site position offset.

site.cex

site name size.

site.col

site colour.

site.order

order of sites within each river. Alphabetical order ("A"), river flow left ("L"), river flow right ("R").

site.srt

site label rotation in degrees.

rvr.shw

show river labels (TRUE) or not (FALSE).

rvr.ofs

river label position offset.

rvr.cex

river label size.

rvr.col

river label colour.

rvr.t.b

location of river label. "t" for top (above) and "b" for below (bottom).

rvr.order

order of rivers. Alphabetical order (NA) or a vector of custom order.

rvr.srt

river label rotation in degrees.

par.shw

show parameter labels (TRUE) or not (FALSE).

par.pos

parameter label position. 1 for below, 2 for left, 3 for above, and 4 for right. See par for details. It overrides par.adj if par.pos is not NULL.

par.ofs

parameter label position offset.

par.cex

parameter label size.

par.adj

parameter label adjustment. One or two values in [0,1] for x and y (optional) adjustment.

par.col

parameter label colour.

par.txt

parameter name.
