ecospace v. 1.2.1 (2017-11-05)

1. Addition of 'increm' argument to calc_metrics() for those wishing to only calculate statistics on the entire sample (instead of incrementally). (Thanks to Craig McClain, Felipe Opazo, Stewart Edie, and Katie Collins for the recommendation.)
2. Improved descriptions of statistics in calc_metrics help file.

Update

ecospace v. 1.1.1 (2017-01-06)

• Slightly faster calculation of H, life habit richness
• Minor fixes: typos in documentation and updated references

New ecospace R package for simulating community assembly and ecological diversification using ecospace frameworks

R Package for Simulating Community Assembly and Ecological Diversification Using Ecospace Frameworks

ecospace is an R package that implements stochastic simulations of community assembly (ecological diversification) using customizable ecospace frameworks (functional trait spaces). Simulations model the 'neutral', 'redundancy', 'partitioning", and "expansion" models of Bush and Novack-Gottshall (2012) as implemented in Novack-gottshall (In pressA,B). The package provides a wrapper to calculate common ecological disparity and functional diversity statistical dynamics as a function of species richness. Functions are written so they will work in a parallel-computing environment.

The package also contains a sample data set, functional traits for Late Ordovician (Type Cincinnatian) fossil species from the Kope and Waynesville formations.
