Example of data from threespine Stickleback gut contents


Example of a raw data matrix to be used with the import.RInSp procedure. Data are from Bolnick and Paull (2009), studying individual specialization in threespine Stickleback (Gasterosteus aculeatus) from 5 sites within one lake in British Columbia. Data columns include:

- FishID: a unique identifier for each individual fish;

- Site: A-E, five locations around the lake where fish were collected;

- Mass: fish mass in grams;

- Standard.length, Body.width, gape.width: fish dimensions in centimetres;

- raker.number: gill raker number;

- raker.length: gill raker length (mm);

- Sex: sex;

- MicrogN, DeltaAir, MicrogC, DeltaPDB: stable isotope data for C and N stable isotope ratios.

All other columns are counts of prey categories in Stickleback stomach contents.
