fulmarin: Fulmarin petrels data

In CajoterBraak/Gendis2unmix: Calculates a generalized discriminant function to unmix two classes, typically sexes of birds

Fulmarin petrels data

Description

The dataframe fulmarin contains measurements on Fulmarine petrels with sex known from dissection or, for Snow Petrels, observation. The variables are as follows:

• population study site ID (integer)

  • 1 Northern Fulmar (Fulmarus glacialis), the Netherlands

  • 2 Northern Fulmar (Fulmarus glacialis), Jan Mayen

  • 3 Southern Fulmar (Fulmarus glacialoides), Ardery Island Antarctica

  • 4 Cape Petrel (Daption capense), Ardery Island Antarctica

  • 5 Antarctic Petrel (Thalassoica antarctica), Ardery Island, Antarctica

  • 6 Snow Petrel (Pagodroma nivea), Casey Station, Antarctica

• sex 0 is female; 1 is male

• HB Head Length (mm)

• BD2 Bill Depth at gonys (mm)

• TL Tarsus Length (mm)

• CL Culmen Length (mm).
