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.
To install the CRAN version, use:

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.

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

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)

coord_equal()## Warning: The `guide` argument in `scale_*()` cannot be `FALSE`. This was deprecated in
## ggplot2 3.3.4.
## ℹ Please use "none" instead.
## Warning: ggrepel: 4 unlabeled data points (too many overlaps). Consider
## increasing max.overlaps
pythag <- pythag %>%
left_join(teamcolors, by = "name")
with(pythag, plot(wpct, exp_wpct, bg = primary, col = secondary, pch = 21, cex = 3))
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 <�]8;;https://github.com/beanumber/teamcolors/issues�https://github.com/beanumber/teamcolors/issues�]8;;�>.
To view color palettes for college teams, use the show_ncaa_col()
function.
show_ncaa_col()
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.

num_teams = n(),
num_logos = sum(!is.na(logo))
