stackedpoly: Plot Stacked and Filled Polygons

In tpetzoldt/rodeoExt: Extensions to the 'rodeo' Package

Description

Plot time series as stacked polygons with color fill and/or shading.

Usage

stackedpoly(x, columns, density = NA, angle = 45, border = NA, col = NA,
  xlab = "x values", ylab = "y values", ...)

Arguments

x	object of class data.frame, the first column is used as x-axis.
columns	vector of column names in appropriate order that are plotted
density	the density of shading lines, in lines per inch. The default value of NULL means that no shading lines are drawn. A zero value of density means no shading nor filling whereas negative values and NA suppress shading (and so allow color filling).
angle	the slope of shading lines, given as an angle in degrees (counter-clockwise).
border	border of the polygon
col	the color for filling the polygon. The default, NA, is to leave polygons unfilled, unless density is specified. (For back-compatibility, NULL is equivalent to NA.) If density is specified with a positive value this gives the color of the shading lines.
xlab	label of the x axis
ylab	label of the y axis
...	further arguments passed to the polygon.

Examples

## test data
set.seed(135)
dat <- data.frame(time = seq(7, 365, 14),
                  y1 = runif(26, min=1, max=10),
                  y2 = runif(26, min=0, max=15),
                  y3 = runif(26, min=0, max=2)
)


##' example palette
palette <-c("grey", "brown", "green", "yellow", "yellowgreen",
            "darkgreen", "blue", "black", "red", "grey", "red", "orange",
            "pink", "cyan"
)


## usage
stackedpoly(dat, c("y1", "y2", "y3"), col=palette)

## polygons with border
stackedpoly(dat, c("y1", "y2", "y3"), col=palette, border="black")

## optional plotting parameters
stackedpoly(dat, c("y1", "y2", "y3"), col=palette, ylim=c(0,50), main="Phytoplankton")

## changed order
stackedpoly(dat, c("y3", "y2", "y1"), col=palette, main="Phytoplankton")

## hatched area
stackedpoly(dat, c("y3", "y2", "y1"), density=c(20, 20, 40),
            angle=c(0, 90, 45), ylim=c(0,50), border=palette, main="Phytoplankton")
