foodweb.plot: Plot the streambugs "foodweb" graph.

In streambugs: Parametric Ordinary Differential Equations Model of Growth, Death, and Respiration of Macroinvertebrate and Algae Taxa

Plot the streambugs "foodweb" graph.

Description

Plot the "foodweb" graph depicting interactions between ODE variables in a streambugs model.

Usage

foodweb.plot(
  y.names,
  par,
  file = NA,
  cex = 1,
  font = 1,
  title = "",
  lwd = 1,
  bg = colors()[1],
  lcol = colors()[555],
  ncrit = 8,
  lcrit = 20,
  survivals = NA,
  observed = NA,
  texts = TRUE,
  pointcol = FALSE,
  ...
)

Arguments

y.names	same as y.names in run.streambugs
par	same as par in run.streambugs
file	optional name of a PDF file to plot to
cex	same as cex in par, consumed by here by multiple text generating functions
font	same as font in par, consumed here by text as a font type for taxa names
title	optional title for the plot
lwd	same as lwd in par, consumed here by lines as a line width for the "food web" edges
bg	same as bg in par
lcol	same as col in par, consumed here by lines as a line color for the "food web" edges
ncrit	number of inverts in one line at which they are shifted up and down, alternating
lcrit	number of letters/characters of state names which are plottet at level 2
survivals	vector with the entries "survived" or "extinct" for all state variables with names matching names of taxa state variables and "SusPOM"
observed	vector with the entries "never"/"notobserved", "observed","sometimes", "always", or NA/"NA" for all state variables, with names matching names of taxa state variables and "SusPOM"
texts	if to plot as "food web"nodes as texts with taxa names; otherwise, plot points
pointcol	if to color text or point nodes using Eawag coloring scheme (eawagfarben); otherwise plot all in the same color
...	additional arguments for the pdf graphics device, relevant only if file argument was given.

Examples

model <- streambugs.example.model.toy()
foodweb.plot(model$y.names, model$par, cex=1.1, title="complete foodweb", ncrit=8,
    lcrit=7, lwd=2, bg="white", lcol="blue", font=2)
