ggcharts

Overview

ggcharts provides a high-level ggplot2 interface for creating common charts. Its aim is both simple and ambitious: shorten the distance from data visualization idea to actual plot. How so? By taking care of a lot of data preprocessing, obscure ggplot2 details and plot styling for you. The resulting plots are ggplot objects and can be further customized using any ggplot2 function.

Installation

The package is available from CRAN.

install.packages("ggcharts")

Alternatively, you can install the latest development version from GitHub.

if (!"remotes" %in% installed.packages()) {
  install.packages("remotes")
}
remotes::install_github("thomas-neitmann/ggcharts", upgrade = "never")

Why ggcharts?

Thanks to ggplot2 you can create beautiful plots in R. However, it can often take quite a bit of effort to get from a data visualization idea to an actual plot. As an example, let’s say you want to create a faceted bar chart displaying the top 10 within each facet ordered from highest to lowest. What sounds simple is actually pretty hard to achieve. Have a look:

library(dplyr)
library(ggplot2)
library(ggcharts)
data("biomedicalrevenue")

biomedicalrevenue %>%
  group_by(year) %>%
  top_n(10, revenue) %>%
  ungroup() %>%
  mutate(company = tidytext::reorder_within(company, revenue, year)) %>%
  ggplot(aes(company, revenue)) +
  geom_col() +
  coord_flip() +
  tidytext::scale_x_reordered() +
  facet_wrap(vars(year), scales = "free_y")

That’s a lot of code! And you likely never heard of some of the functions involved. With ggcharts you can create the same plot (actually an even better looking one) in a single line of code.

bar_chart(biomedicalrevenue, company, revenue, facet = year, top_n = 10)

That’s the beauty of ggcharts: shortening the distance between data visualization idea and actual plot as much as possible.

Features

Currently ggcharts includes the following functions:

• bar_chart()
• diverging_bar_chart()
• column_chart()
• lollipop_chart()
• diverging_lollipop_chart()
• dumbbell_chart()
• pyramid_chart()

You can learn more about these functions here.

These binaries (installable software) and packages are in development.
