cfbplotR

The code for this package was copied heavily from nflplotR with minor changes to support college football team logos.

The goal of cfbplotR is to provide functions and geoms that help visualization of CFB related analysis. It provides a ggplot2 geom that does the heavy lifting of plotting CFB logos in high quality, with correct aspect ratio and possible transparency.

Installation

You can install the development version from GitHub with:

if (!require("remotes")) install.packages("remotes")
remotes::install_github("Kazink36/cfbplotR")

Using cfbplotR

You can follow this tutorial to see several different uses for cfbplotR. The key function in the package is geom_cfb_logo() which will add college football team logos to a ggplot.

library(cfbplotR)
library(ggplot2)
team <- valid_team_names()
team <- team[1:32]
df <- data.frame(
  a = rep(1:8, 4),
  b = sort(rep(1:4, 8), decreasing = TRUE),
  teams = team
)

# keep alpha == 1 for all teams including an "A"
matches <- grepl("A", team)
df$alpha <- ifelse(matches, 1, 0.9)
# change color of all teams including an "o" to black and white
matches <- grepl("o", team)
df$color <- ifelse(matches, "b/w",NA)

 ggplot(df, aes(x = a, y = b)) +
   geom_cfb_logos(aes(team = teams, color = color, alpha = alpha), width = 0.075) +
   geom_label(aes(label = teams), nudge_y = -0.35, alpha = 0.5) +
   scale_color_identity() +
   scale_alpha_identity() +
   theme_void()
