Harry Potter Colour Map.

Description

This function creates a vector of n equally spaced colors along the 'HP colour map' of your selection

Usage

hp(
  n,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  option = "Always",
  house = NULL
)

hp_pal(
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  option = "Always",
  house = NULL
)

harrypotter(
  n,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  option = "Always",
  house = NULL
)

Arguments

n

The number of colors (\ge 1) to be in the palette.

alpha

The alpha transparency, a number in [0,1], see argument alpha in hsv.

begin

The (corrected) hue in [0,1] at which the hp colormap begins.

end

The (corrected) hue in [0,1] at which the hp colormap ends.

direction

Sets the order of colors in the scale. If 1, the default, colors are ordered from darkest to lightest. If -1, the order of colors is reversed.

option

A character string indicating the colourmap from a option to use. Four houses are available: "Gryffindor", "Slytherin", "Ravenclaw" and "Hufflepuff".

house

Depcreated. Use 'option' instead.

Details

Semi-transparent colors (0 < alpha < 1) are supported only on some devices: see rgb.

Value

hp returns a character vector, cv, of color hex codes. This can be used either to create a user-defined color palette for subsequent graphics by palette(cv), a col = specification in graphics functions or in par.

Original 'Harry Potter' colour map

Description

A dataset containing some colour palettes inspired on the Harry Potter Universe

Usage

hp.map

Format

A data frame containing all the colours used in the palette:

V1: Red value
V2: Green value
V3: Blue value
option: It is intended to be a general option for choosing the specific colour palette.

Available Palettes.

Description

This list contains all the available palettes in the 'harrypotter' package.

Usage

hp_palettes

Format

A list containing all palettes color codes.

Harry Potter colour scales

Description

Uses the Harry Potter color scale.

Usage

scale_color_hp(
  option = "Always",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  discrete = FALSE,
  house = NULL
)

scale_colour_hp(
  option = "Always",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  discrete = FALSE,
  house = NULL
)

scale_colour_hp_d(
  option = "Always",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1
)

scale_color_hp_d(
  option = "Always",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1
)

scale_fill_hp_d(
  option = "Always",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1
)

scale_fill_hp(
  option = "Always",
  ...,
  alpha = 1,
  begin = 0,
  end = 1,
  direction = 1,
  discrete = FALSE,
  house = NULL
)

Arguments

option

A character string indicating the colourmap to use. Four houses are available: "Gryffindor", "Slytherin", "Ravenclaw" and "Hufflepuff".

...

parameters to discrete_scale or scale_fill_gradientn

alpha

pass through parameter to hp

begin

The (corrected) hue in [0,1] at which the hp colormap begins.

end

The (corrected) hue in [0,1] at which the hp colormap ends.

direction

Sets the order of colors in the scale. If 1, the default, colors are as output by hp_pal. If -1, the order of colors is reversed.

discrete

generate a discrete palette? (default: FALSE - generate continuous palette)

house

A character string indicating the colourmap from a option to use. This parameter is deprectaed, 'option' should be used instead. Four houses are available: "Gryffindor", "Slytherin", "Ravenclaw" and "Hufflepuff".

Details

For discrete == FALSE (the default) all other arguments are as to scale_fill_gradientn or scale_color_gradientn. Otherwise the function will return a discrete_scale with the plot-computed number of colors.
