Color and Fill Scales for College Basketball Teams and Conferences

These functions provide color and fill scales for ggplot2 based on college basketball team and conference colors.

Usage

scale_color_cbb_teams(
  type = c("primary", "secondary"),
  values = NULL,
  ...,
  aesthetics = "colour",
  breaks = ggplot2::waiver(),
  na.value = "grey50",
  guide = NULL,
  alpha = NA
)

scale_colour_cbb_teams(
  type = c("primary", "secondary"),
  values = NULL,
  ...,
  aesthetics = "colour",
  breaks = ggplot2::waiver(),
  na.value = "grey50",
  guide = NULL,
  alpha = NA
)

scale_fill_cbb_teams(
  type = c("primary", "secondary"),
  values = NULL,
  ...,
  aesthetics = "fill",
  breaks = ggplot2::waiver(),
  na.value = "grey50",
  guide = NULL,
  alpha = NA
)

scale_color_cbb_conferences(
  type = c("primary", "secondary"),
  values = NULL,
  ...,
  aesthetics = "colour",
  breaks = ggplot2::waiver(),
  na.value = "grey50",
  guide = NULL,
  alpha = NA
)

scale_colour_cbb_conferences(
  type = c("primary", "secondary"),
  values = NULL,
  ...,
  aesthetics = "colour",
  breaks = ggplot2::waiver(),
  na.value = "grey50",
  guide = NULL,
  alpha = NA
)

scale_fill_cbb_conferences(
  type = c("primary", "secondary"),
  values = NULL,
  ...,
  aesthetics = "fill",
  breaks = ggplot2::waiver(),
  na.value = "grey50",
  guide = NULL,
  alpha = NA
)

Arguments

type

The type of color scale, either "primary" or "secondary".

values

A named list of colors to be used if overriding the default team or conference colors.

...

Arguments passed on to discrete_scale

palette

A palette function that when called with a single integer argument (the number of levels in the scale) returns the values that they should take (e.g., scales::pal_hue()).

breaks

One of:

• NULL for no breaks

• waiver() for the default breaks (the scale limits)

• A character vector of breaks

• A function that takes the limits as input and returns breaks as output. Also accepts rlang lambda function notation.

limits

One of:

• NULL to use the default scale values

• A character vector that defines possible values of the scale and their order

• A function that accepts the existing (automatic) values and returns new ones. Also accepts rlang lambda function notation.

drop

Should unused factor levels be omitted from the scale? The default, TRUE, uses the levels that appear in the data; FALSE uses all the levels in the factor.

na.translate

Unlike continuous scales, discrete scales can easily show missing values, and do so by default. If you want to remove missing values from a discrete scale, specify na.translate = FALSE.

na.value

If na.translate = TRUE, what aesthetic value should the missing values be displayed as? Does not apply to position scales where NA is always placed at the far right.

aesthetics

The names of the aesthetics that this scale works with.

scale_name

The name of the scale that should be used for error messages associated with this scale.

labels

One of:

• NULL for no labels

• waiver() for the default labels computed by the transformation object

• A character vector giving labels (must be same length as breaks)

• An expression vector (must be the same length as breaks). See ?plotmath for details.

• A function that takes the breaks as input and returns labels as output. Also accepts rlang lambda function notation.

call

The call used to construct the scale for reporting messages.

super

The super class to use for the constructed scale

aesthetics

The ggplot2 aesthetic to apply the scale to, defaults to "colour" or "fill".

breaks

A set of breaks for the scale, defaults to ggplot2::waiver().

na.value

The color to use for missing values.

guide

A guide for the scale, such as a legend.

alpha

Transparency level 0-1, applied to all colors if not NA.

Value

A ggplot2 color or fill scale.
