cheddar | R Documentation |
Cheddar provides a flexible, extendable representation of an ecological community and a range of functions for analysis and visualisation, focusing on food web, body mass and numerical abundance data. It also allows inter-web comparisons such as examining changes in community structure over environmental, temporal or spatial gradients.
Details of differences between versions of Cheddar are in the the online release history: https://github.com/quicklizard99/cheddar/blob/master/release_history.md.
