plot.conceptmap: Plotting a conceptmap

In comato: Analysis of Concept Maps and Concept Landscapes

Description

plot plots a concept map. Includes finding a good layout based on communities and a circular layout. Is especially suited for plotting larger concept maps, in particular amalgamations.

Usage

## S3 method for class 'conceptmap'
plot(x, edge.labels = T, max.label.len = 25,
  scale = 1, layout = NULL, ...)

Arguments

x	A conceptmap object.
edge.labels	If TRUE, the labels of edges will be plotted as well.
max.label.len	The maximal length of labels (in characters) that are plotted completely. Longer labels will be shortend by "...".
scale	Overall scaling factor that is applied to the plot.
layout	If not NULL, must either be one of "fruchterman.reingold", "kamada.kawai", "spring" or "reingold.tilford" or a numeric matrix. If it is a string, the corresponding layouting algorithm of the igraph package will be called. If it is a numeric matrix, it must contain a row for each concept and two columns that determine the x and y coordinates of this concept. Then this layout will be used directly.

Examples

#Create concept map from a random graph
require("igraph")
g1 = set.vertex.attribute(erdos.renyi.game(5, 0.7, type="gnp"), "name", value=1:5)
E(g1)$name <- rep("", length(E(g1)))
plot(conceptmap(g1), edge.labels=FALSE, layout="kamada.kawai")
