Discrete colour scales for PHS — scale_colour_discrete

The default discrete colour scale for use in PHS

Usage

scale_colour_discrete_phs(
  ...,
  type = "seq",
  palette = 1,
  direction = 1,
  aesthetics = "colour"
)

scale_color_discrete_phs(
  ...,
  type = "seq",
  palette = 1,
  direction = 1,
  aesthetics = "colour"
)

Arguments

...: Additional parameters passed on to the scale type
type: either "seq" (sequential) or "qual" (qualitative). Defaulted as "seq". Please see phs_palette_types for more details.
palette: a number describing which palette to use within that type. Defaulted as 1 referring to the first palette "main-purples" in type "seq". It can also be the actual name of the palette e.g. main-purples. Please see phs_palettes for more details.
direction: either be 1 (following the palette order) or -1 (reversing the palette order). Defaulted as 1.
aesthetics: defaulted as "colour"

Details

There are a list of discrete colour scales that can be used for PHS charts, such as main-purples which contains phs-purple, phs-purple-80, phs-purple-50, phs-purple-30 and phs-purple-10.

Examples

df <- mtcars
df[,'cyl'] <- as.factor(df[,'cyl'])
ggplot2::qplot(mpg, wt, data = df, colour = cyl) +
scale_colour_discrete_phs(palette = "main")


df <- mtcars
df[,'cyl'] <- as.factor(df[,'cyl'])
ggplot2::qplot(mpg, wt, data = df, colour = cyl) +
scale_color_discrete_phs(palette = "main")
