Indicator I10 : Size frequencies by decade

Description

This indicator build a graph relative contribution of size frequencies in catches for a species by decade. An associated RDF file is also produced.

Data can come from http://mdst-macroes.ird.fr:8080/constellation/WS/wfs/tuna_atlas using the layer named "i9i10_mv".

Use

library(IRDTunaAtlas)
