ggvegan (development version)

New Functions

• autolayer.envfit is a new function to add vegan::envfit() results to an ordiggplot() graph.

• autolayer.ordisurf is a new function to add vegan::ordisurf() contours and raster surface (optional) to any ordination graph.

• geom_ordi_repel is a new layer function for ordiggplot() to draw points (optionally) at the ordination scores and repel their text labels to avoid over-plotting.

New features

• fortify.radfit and autoplot.radfit methods implemented providing support for vegan::radfit() and vegan::as.rad().

• ordiggplot() adds mapping score to colour for automatic colouring of layers analogously to autoplot methods.

• geom_ordi_text() and geom_ordi_label() accept vegan::envfit() result as an argument data= to draw locations of centroids of factor levels in an ordiggplot() layer.

• geom_ordi_arrow() accepts vegan::envfit() result as an argument data= for labelled (optionally) arrows of fitted vectors in an ordiggplot() layer.

Bug fixes

• ggplot2 would report a warning about dropped aesthetics when StatVectorfit was run. #43 Fixed by @jarioksa in #44.

• geom_ordi_arrow did not pass weights of CCA or other weighted ordination methods to StatVectorfit.
