football: College football games network (undirected)

In geomnet: Network Visualization in the 'ggplot2' Framework

Description

A list of two datasets, vertices and edges, containing data on Division I college football games in the Fall 2000 season. The variables are as follows:

Usage

football

Format

A list of two data frames:

• the edges data set consists of three variables of length 613:

  • from, to: Character variables describing the teams playing in the game

  • same.conf: An indicator variable that is 1 if the two teams are in the same conference and 0 otherwise.

• the vertices data set consists of two variables with information on 115 Division I schools:

  • label: Character variable containing the school names

  • value: Character variable containing the conference of the schools

Examples

# data step: merge vertices and edges
ftnet <- merge(
  football$edges, football$vertices,
  by.x = "from", by.y = "label", all = TRUE
)

# label independent schools
ftnet$schools <- ifelse(ftnet$value == "Independents", ftnet$from, "")

library(geomnet)
library(dplyr)
# create data plot
ggplot(data = ftnet,
       aes(from_id = from, to_id = to)) +
  geom_net(
    aes(
      colour = value, group = value,
      linetype = factor(1-same.conf),
      label = schools
    ),
    linewidth = 0.5,
    size = 5, vjust = -0.75, alpha = 0.3,
    layout.alg = 'fruchtermanreingold'
  ) +
  theme_net() +
  theme(legend.position = "bottom") +
  scale_colour_brewer("Conference", palette = "Paired")
