ambiR, a new R-package, is now available and provides an efficient tool for calculating the AMBI-index and the multivariate M-AMBI, based upon species data and benthic fauna. AMBI (AZTI’s Marine Biotic Index) was originally developed by Ángle Borja et al. (2000) and is widely used in monitoring marine ecology. The R-package also enables calculating different versions of the Danish Quality Index (DKI), an index derived from AMBI.

ambiR capabilities:

• AMBI() – calculate AMBI-index
• MAMBI() – calculates the multivariate M-AMBI index
• Hdash() – calculates H’, the Shannon diversity index
• DKI2()  – calculates the salinity-normalised Danish quality index DKI (v2)
•  DKI() – calculates the Danish quality index DKI

The package also includes a build in species list.

Installation guide and examples on use are provided in the following link.
