Examples

library(tidyverse)
library(ggplot2)

#devtools::install_github("connorrothschild/bbdata")
library(bbdata)
library(gapminder)

bbd_font_install(device = 'win', force = TRUE)

data <- gapminder %>% 
  dplyr::filter(gapminder$country %in% c("Italy", "Japan", "Norway", "Mexico", "United States")) %>%
  dplyr::mutate(year = as.Date(paste(year, "-01-01", sep = "", format='%Y-%b-%d')))

set_bbd_theme()

ggplot(data = data, aes(x = year, y = gdpPercap/1000, fill = country)) +
  geom_area() +
  scale_x_date(expand = c(0,0)) +
  bbd_fix_bars() +
  labs(title = "GDP Per Capita Over Time",
       subtitle = "Using the BBD Color Palette",
       x = "Year",
       y = "GDP Per Capita\n(thousands of $)",
       fill = "Country",
       caption = "Source: Gapminder")

An example using ggtext:

#devtools::install_github("clauswilke/ggtext")
library(ggtext)

data <- gapminder %>% 
  filter(year == 2007) %>% 
  mutate(rank = rank(gdpPercap)) %>% 
  filter(rank > 132)

ggplot(data, aes(x = reorder(country, gdpPercap), 
                 y = gdpPercap, 
                 fill = ifelse(country == "Norway", "1", "0"))) +
  geom_col(show.legend = FALSE) +
  scale_y_continuous(expand = c(0, 0), labels = scales::dollar) +
  coord_flip() +
  labs(y = "GDP per capita",
       x = element_blank(),
       title = "The Wealthiest Countries",
       subtitle = "<span style='color:#00315B'>**Norway**</span> leads in GDP per capita",
       caption = "Source: Gapminder") +
  theme(plot.subtitle = element_markdown(lineheight = 1.1))

Palettes

p1 <- view_palette(palette = palette_bbd_main) + ggtitle("Categorical")
p2 <- view_palette(palette = palette_bbd_diverging) + ggtitle("Diverging")
p3 <- view_palette(palette = palette_bbd_sequential) + ggtitle("Sequential")

gridExtra::grid.arrange(p1, p2, p3, nrow = 1)
