An R package of functional summaries useful for analysing multitype point patterns, mainly motivated by biodiversity analysis.

Global and local versions of

• Shannon index
• Simpson index
• Mingling -''-
• Mean Compositional index

Also

• ISAR i.e. count of alien types around 'average point' of chosen type
• Dixon's test
• Biomass sums, weighted ISAR

Local versions support the usual "upto distance r" as well as "k-nearest", Gabriel and Delaunay graphs.
