plot_hierarchy_shape {aniDom} R Documentation

## Plots the shape of a dominance hierarchy from empirical data

### Description

This function takes a set of winners and losers from observed interactions and plots the probability of the dominant individual in an interaction winning given the difference in rank to the subordinate in the same interaction.

### Usage

```plot_hierarchy_shape(identity, rank, winners, losers, fitted = FALSE)
```

### Arguments

 `identity` A vector containing the identities of all individuals in the data. `rank` A vector giving the ranks for each individual (in the same order as the identities). `winners` A vector giving the identity of the winner for each interaction. `losers` A vector giving the identity of the loser for each interaction in the same order as the winners. `fitted` A Boolean (TRUE/FALSE) describing whether to add a fitted line to the plot

### Details

This function is useful for examining how the probability of winning is shaped by the difference in rank. The shape of this graph provides information about the shape of the dominance hierarchy.

### Value

This function will return the data for x (difference in rank) and y (probability of dominant winning) coordinates of the plot as a data frame.

### Examples

```
par(mfrow=c(1,2))

# Set population size
N <- 20

# Set shape parameters
a = 15
b = 3

# See what this looks like
plot_winner_prob(1:N,a,b)

# Generate some input data
data <- generate_interactions(N,400,a,b)

# See what the hierarchy looks like from the output data
winners <- data\$interactions\$Winner
losers <- data\$interactions\$Loser
identities <- data\$hierarchy\$ID
ranks <- data\$hierarchy\$Rank
shape <- plot_hierarchy_shape(identities,ranks,winners,losers,fitted=TRUE)

# Data is contained in shape
shape
