ecoCopula : and R package for fast ordination and graphical modelling

I have been a bit tardy putting up October's Eco-Stats Lab, which was on the ecoCopula package (now on CRAN). ecoCopula does fast model based ordination, and lets you create 'graphs' of species associations (interactions) from co-occurrence data. See the vignette for a walk though.

plotenvelope - making sense of diagnostic plots using simulation envelopes

This month's Eco-Stats Lab is on the plotenvelope function in the ecostats package.  This function can be used (in place of plot) to construct residual plots of most common fitted model objects in R, including global simulation envelopes around fitted values (or around smoothers) on the plot.  These slides explain what this all means.
