In UI-Research/urbnthemes: Additional theme and utilities for "ggplot2" in the Urban Institute style

urbnthemes

Overview

urbnthemes is a set of tools for creating Urban Institute-themed plots and maps in R. The package extends ggplot2 with print and map themes as well as tools that make plotting easier at the Urban Institute.

A comprehensive set of examples is available at the Urban Institute R Users Group website.

Installation

install.packages("devtools")
devtools::install_github("UI-Research/urbnthemes", build_vignettes = TRUE)

Fonts

The Urban Institute uses Lato font for publications. After installing urbnthemes, submit urbnthemes::lato_test() to see if Lato is imported and registered.

If Lato isn’t imported and registered, install Lato and then submit urbnthemes::lato_install(). If you are on a Windows, you may need to install ghostscript and then submit Sys.setenv(R_GSCMD = "link to the ghostscript .exe") before running urbnthemes::lato_install().

Waffle charts with glyphs require fontawesome. fontawesome_test() and fontawesome_install() are the fontawesome versions of the above functions. Be sure to install fontawesome from here.

Usage

Always load library(urbnthemes) after library(ggplot2) or library(tidyverse).

library(tidyverse)
library(urbnthemes)

ggplot(data = mtcars, mapping = aes(factor(cyl))) +
  geom_bar() + 
  scale_y_continuous(expand = expand_scale(mult = c(0, 0.1))) +
  labs(x = "Number of Cylinders",
       y = "Count") +
  remove_ticks()

                     breaks = c(1952 + 0:12 * 5), 
                     limits = c(1952, 2007)) +

                     breaks = 0:8 * 5000,
                     labels = scales::dollar, 
                     limits = c(0, 40000)) +
  labs(x = "Year",
       y = "Per capita GDP (US dollars)")

txhousing %>%
  filter(city %in% c("Austin","Houston","Dallas","San Antonio","Fort Worth")) %>%
  group_by(city, year) %>%
  summarize(sales = sum(sales)) %>%
  ggplot(aes(x = year, y = sales, fill = city)) +
  geom_area(position = "stack") +
  scale_x_continuous(expand = expand_scale(mult = c(0, 0)),
                     limits = c(2000, 2015),
                     breaks = 2000 + 0:15) +  
  scale_y_continuous(expand = expand_scale(mult = c(0, 0.2)), 
                     labels = scales::comma) +
  labs(x = "Year",
       y = "Home sales")
