Description

This indicator produce a graph of annual catches by gear for each species present in the input data. An associated RDF file is also produced.

Use

require(IRDTunaAtlas)
#fetch data from IRD WFS for indicators I2, with restriction on species="YFT"
df <- readData(connectionType="remote", dataType="WFS",
               url="http://mdst-macroes.ird.fr:8080/constellation/WS/wfs/tuna_atlas",
               layer="ns11:i1i2_mv", 
               ogcFilter='<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml"><ogc:PropertyIsEqualTo><ogc:PropertyName>species</ogc:PropertyName><ogc:Literal>YFT</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Filter>')
#build the I2 indicator
result <- Atlas_i2_SpeciesByGear(df=df, 
                                 yearAttributeName="year", 
                                 gearTypeAttributeName="gear_type",
