foodweb: visualisation and analysis of food web networks

Calculates twelve commonly-used, basic measures of food web network structure from binary, predator-prey matrices: species richness, connectance, total number of links, link density, number of trophic positions, predator:prey ratio, and fraction of carnivores, herbivores, top species and intermediate species. Employs food web language in the code and output, translates between a couple of common food web formats, can handle food webs consisting of multiple levels, and can automate the analysis for a large number of webs. The program produces 3-dimensional graphs of high quality that can be customized by the user.
