In UofTCoders/eeb430.2017.JuniorCoders: Team Junior Coders Final Report for EEB430 at UofT

possible analysis

• biomass vs. lattitude: converge lattitude into number, try simple linear model
• biomass/length vs. feeding behaviour: chi-square ?
• predator-prey mass: furthur analysis on each species/ confidence interval
• feeding behaviour vs. location/temp: bar chart?/pie chart?
• biomass/length vs. depth: linear model

## See spec(...) for full column specifications.

possible figure

• figure 1:biomass vs. feeding type, box plot

• figure 2:predator mass vs. prey mass in log scale, facet by feeding type with linear regression.

facet by taxon/species can also be added.

• figure 3:predator mass vs. annual average temperature
