CARTOcolor palettes

Description

Creates a color palette from CARTOcolor

Usage

carto_pal(n = NULL, name, ...)

Arguments

n	Number of different colors in the palette, minimum depending on palette (2 or 3), maximum depending on palette (7 or 11)
name	A palette name
...	Additional arguments for grDevices::colorRampPalette

Value

A character vector

Examples

my_colors1 = carto_pal(7, "Burg")
my_colors1

my_colors2 = carto_pal(17, "Burg")
my_colors2

my_colors3 = carto_pal(17, "Safe")
my_colors3

CARTOcolor palettes viewer

Description

Displays a set of the color palettes from CARTOcolor

Usage

display_carto_all(n = NULL, type = "all", colorblind_friendly = NULL)

Arguments

n	Number of different colors in the palette, minimum depending on the palette (2 or 3), maximum depending on the palette (7 or 11)
type	Type of the palette, can be "quantitative", "diverging", "qualitative", "aggregation", or "all"
colorblind_friendly	if TRUE, display only colorblind friendly palettes

CARTO color scales

Description

CARTO color scales

Usage

scale_color_carto_c(
  ...,
  type = "quantitative",
  palette = 1,
  direction = 1,
  na.value = "#e9e9e9",
  guide = "colourbar"
)

scale_color_carto_d(
  ...,
  type = "qualitative",
  palette = 1,
  direction = 1,
  na.value = "#e9e9e9"
)

scale_colour_carto_c(
  ...,
  type = "quantitative",
  palette = 1,
  direction = 1,
  na.value = "#e9e9e9",
  guide = "colourbar"
)

scale_colour_carto_d(
  ...,
  type = "qualitative",
  palette = 1,
  direction = 1,
  na.value = "#e9e9e9"
)

scale_fill_carto_c(
  ...,
  type = "quantitative",
  palette = 1,
  direction = 1,
  na.value = "#e9e9e9",
  guide = "colourbar"
)

scale_fill_carto_d(
  ...,
  type = "qualitative",
  palette = 1,
  direction = 1,
  na.value = "#e9e9e9"
)

Arguments

...	Other arguments passed on to ggplot2::discrete_scale() or ggplot2::continuous_scale() to control name, limits, breaks, labels and so forth
type	One of \"aggregation\", \"diverging\", \"qualitative\", or \"quantitative\"
palette	If a string, will use that named palette. If a number, will index into the list of palettes of appropriate type
direction	Sets the order of colors in the scale. If 1, the default, colors are as output by carto_pal(). If -1, the order of colors is reversed
na.value	Missing values will be replaced with this value.
guide	A function used to create a guide or its name. See guides() for more information.
