John F. Quensen developed ggordiplots to add features from the vegan package to ggplot2 ordination plots. The package includes functions like ordiarrows(), ordiellipse(), ordihull(), ordispider(), and ordisurf(). It also provides gg_ordibubble() to size points relative to an environmental variable.
Use Cases
- Add arrows to ordination plots based on ordiarrows() functionality
- Draw ellipses or hulls around groups based on ordiellipse() and ordihull()
- Create spider plots connecting points to centroids based on ordispider()
- Size points relative to environmental variables based on gg_ordibubble()
- Add smooth surfaces to ordination plots based on ordisurf()
Strengths
- Provides ggplot2 versions of five specific vegan ordination functions
- Includes an additional function, gg_ordibubble(), for environmental variable visualization
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
