<!-- badges: start -->
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.

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_point(shape = 21, size = 3) +

caption = "Source: Lahman baseball database. Using teamcolors R pkg"
) +

Base R

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.
