plot_diet: Plot contribution of diet contents for each functional group.

Description Usage Arguments Value See Also Examples

Visualize diet proportions form predator and prey perspective. The upper panel plot shows the predator perspective while the lower panel plot shows the prey perspective for a given group. Please note that this function only works with models based on the trunk code. Bec_dev models should use plot_diet_bec_dev to get an indication of the feeding interactions.

1 2	plot_diet(bio_consumed, species = NULL, wrap_col = "agecl", combine_thresh = 7)

`bio_consumed`	Consumed biomass of prey groups by predatorgroup and agecl in tonnes for each timestep and polygon. Dataframe with columns 'pred', 'agecl', 'polygon', 'time', 'prey'. Consumed biomass in [t] is stored in column 'atoutput'. Should be generated with `link{calculate_consumed_biomass}`.
`species`	Character string giving the acronyms of the species you aim to plot. Default is `NULL` resulting in all available species being ploted.
`wrap_col`	Character specifying the column of the dataframe to be used as multipanel plot. Default is `"agecl"`.
`combine_thresh`	Number of different categories to plot. Lets say predator X has eaten 20 different prey items. If you only want to show the 3 most important prey items set `combine_thresh` to 3. As rule of thumb values < 10 are useful otherwise to many colors are used in the plots. Default is `7`.
