Using with {ggplot2}

Install from CRAN using:

install.packages("PrettyCols")

Or install the development version using:

remotes::install_github("nrennie/PrettyCols")

Then load into R:

library(PrettyCols)

Set up a simple data frame to use for an example plot:

library(ggplot2)
df <- data.frame(type = c("A", "B", "C"),
                 value = c(1, 2, 3))

To change the fill or colour for discrete variables:

ggplot(data = df,
       mapping = aes(x = type, y = value, fill = type)) +
  geom_col() +
  scale_fill_pretty_d(name = "Blues")

ggplot(data = df,
       mapping = aes(x = type, y = value, colour = type)) +
  geom_col(size = 2, fill = "white") +
  scale_colour_pretty_d(name = "Blues")
#> Warning: Using `size` aesthetic for lines was deprecated in ggplot2 3.4.0.
#> ℹ Please use `linewidth` instead.

To change the fill or colour for continuous variables:

ggplot(data = df,
       mapping = aes(x = type, y = value, fill = value)) +
  geom_col() +
  scale_fill_pretty_c(name = "Purples")

ggplot(data = df,
       mapping = aes(x = type, y = value, colour = value)) +
  geom_col(size = 2, fill = "white") +
  scale_colour_pretty_c(name = "Purples", direction = -1)

To change the legend title:

ggplot(data = df,
       mapping = aes(x = type, y = value, fill = value)) +
  geom_col() +
  scale_fill_pretty_c(name = "Purples", legend_title = "My New Title") +
  theme(legend.title = element_text(colour = "blue"))
