RiverBlock: River Block-Chart

Description

This plots blocks to display qualitative data on the river chart.

Usage

RiverBlock(site, river, distance, value, riverlayout, arrangement,
           pt.shw = FALSE, hw.rat = 1.5, h.gap = 0.05, w.gap = 0.025, 
           block.col = NA, block.lwd = 1, bd.col = "grey20",                    
           par.shw = TRUE, par.pos = 2,
           par.ofs = 1, par.cex =0.6, par.adj = c(1,0.5),
           lbl.shw = TRUE, lbl.cex = 0.7, lbl.adj = c(0.5,2), lbl.ofs = 0.5,
           lbl.col = "black", lbl.srt = 0, lbl.pos = NULL)

Arguments

site

a 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 qualitative variables to be shown on the block-chart.

riverlayout

the output list of RiverLayout or RiverMap.

arrangement

a vector indicating the block number for each line.

pt.shw

show location point (TRUE) or not (FALSE).

hw.rat

the ratio of block height and width in the plotted diagram.

h.gap

vertical gap size between blocks. By default, the vertical gap is river height * 0.05 in each river chart.

w.gap

horizontal gap size between blocks when there is more than one block in each line. By default, the horizontal gap is largest block width * 0.025.

block.col

block colour.

block.lwd

block line width.

bd.col

block border col.

par.shw

show parameter names (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.

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.

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).
