rviewgraph provides an R interface to Alun Thomas's 'ViewGraph' Java graph viewing program.
This package provides an R interface to Alun Thomas's 'ViewGraph' Java graph viewing program.
It takes a graph specified as an incidence matrix, array of edges, or in
and runs a graphical user interface that shows an
animation of a force directed algorithm positioning the vertices in two dimensions.
It works well for graphs of various structure
of up to a few thousand vertices. It's not fazed by graphs that comprise several
components. The coordinates can be read as an
igraph style layout matrix at any time.
The user can mess with the layout using a mouse, preferably one with 3 buttons,
and some keyed commands.
The only function that the user needs to know about in this package is rViewGraph(). It launches the GUI by delegating to specific functions depending on the class of the arguments.
The Java program 'ViewGraph' is contained in Alun Thomas's 'JPSGCS' collection of java programs for statistical genetics and computational statistics. The homepage for 'JPSGCS' is <http://www-genepi.med.utah.edu/~alun/software/index.html>. The documentation page for 'ViewGraph' is at <http://www-genepi.med.utah.edu/~alun/software/docs/ViewGraph.html>.
