teamcolors

R-CMD-check CRAN status

An R package providing color palettes for pro and amateur sports teams. The palettes are provided by Jim Neilsen’s Team Colors website and offered with only minimal alterations. NCAA colors come from teamcolorcodes.com, via the ncaahoopR package. Other sports include the Women’s National Basketball Association, National Women’s Soccer League, and the Canadian Football League.

Install

To install the CRAN version, use:

install.packages(teamcolors)

To install the development version from GitHub, use:

devtools::install_github("beanumber/teamcolors")

Show palettes

Sometimes you need to work with a named vector of colors. Other times you can use the built-in scale_color_teams() and scale_color_fill() functions.

Plot

In baseball, Pythagorean expectation relates expected winning percentage to runs allowed and runs scored. How well does it work?

library(Lahman)
library(tidyverse)
pythag <- Teams %>%
  filter(yearID == 2016) %>%
  select(name, teamID, yearID, W, L, R, RA) %>%
  mutate(
    wpct = W / (W + L), exp_wpct = 1 / (1 + (RA / R)^2),
    # note name discrepancy!
    name = ifelse(name == "Los Angeles Angels of Anaheim", "Los Angeles Angels", name)
  )

ggplot2

ggplot(pythag, aes(x = wpct, y = exp_wpct, color = name, fill = name)) +
  geom_abline(slope = 1, intercept = 0, linetype = 3) +
  geom_point(shape = 21, size = 3) +
  scale_fill_teams(guide = FALSE) +
  scale_color_teams(2, guide = FALSE) +
  ggrepel::geom_text_repel(aes(label = teamID)) +
  scale_x_continuous("Winning Percentage", limits = c(0.3, 0.7)) +
  scale_y_continuous("Expected Winning Percentage", limits = c(0.3, 0.7)) +
  theme_light() +
  labs(
    title = "Real and Pythagorean winning % by team",
    subtitle = paste(first(pull(pythag, yearID)), "MLB Season", sep = " "),
    caption = "Source: Lahman baseball database. Using teamcolors R pkg"
  ) +
  coord_equal()
## Warning: The `guide` argument in `scale_*()` cannot be `FALSE`. This was deprecated in
## ggplot2 3.3.4.
## ℹ Please use "none" instead.
## This warning is displayed once every 8 hours.
## Call `lifecycle::last_lifecycle_warnings()` to see where this warning was
## generated.

## Warning: ggrepel: 3 unlabeled data points (too many overlaps). Consider
## increasing max.overlaps

Base R

pythag <- pythag %>%
  left_join(teamcolors, by = "name")
with(pythag, plot(wpct, exp_wpct, bg = primary, col = secondary, pch = 21, cex = 3))

Key

You can see the color palettes using existing functionality from the scales package, but it won’t show the names of the teams.

scales::show_col(league_pal("mlb"), borders = league_pal("mlb", 2))

So, instead, use show_team_col(). Note that this only shows color palettes for non-NCAA teams.

show_team_col()
## Warning: The `<scale>` argument of `guides()` cannot be `FALSE`. Use "none" instead as
## of ggplot2 3.3.4.
## ℹ The deprecated feature was likely used in the teamcolors package.
##   Please report the issue at <https://github.com/beanumber/teamcolors/issues>.
## This warning is displayed once every 8 hours.
## Call `lifecycle::last_lifecycle_warnings()` to see where this warning was

To view color palettes for college teams, use the show_ncaa_col() function.

show_ncaa_col()

Logos

Links to team logos are provided by (http://www.sportslogos.net/).

teamcolors %>%
  filter(grepl("New Y", name)) %>%
  pull(logo) %>%
  knitr::include_graphics()

Note that we don’t have any coverage for the EPL.

teamcolors %>%
  group_by(league) %>%
  summarize(
    num_teams = n(),
    num_logos = sum(!is.na(logo))
  )
## # A tibble: 10 × 3
