Shiny app to build custom ggplot themes

ggShinyApp

This R Shiny application is designed customize graphing themes for ggplot2. Once the theme is customized to your liking, you can download an R script to distribute to any R users in your organization. The main script is ggplot_styling.R, which must be run once per R session in order to set custom themes for all ggplot graphs. installation_script.R needs to be run once per user (it installs packages and pulls in system fonts).

This application can be run two ways, either locally on your computer or as a hosted shinyapp.

####Running locally

#####To install:

• Run the following commands in your R terminal/ environment.

install.packages(c('shiny','ggplot2','reshape2','RColorBrewer','plyr','stringr','extrafont'))
library(extrafont)
font_import()
loadfonts()

• Clone this repository, and set your R working directory to the cloned repo's parent directory.
• In R, run runApp('ggShinyApp') to launch the app.

#####To run:

• The application will open in your browser. You can use the tabs, drop down menus, and other inputs to customize the example ggplot.
• When you're happy with the theme, use the download links to download the customization scripts.

####Running hosted version You can see a hosted version of the app at https://bchartoff.shinyapps.io/ggShinyApp/. This version functions the same as the local version with one exception, it does not import your local system fonts (or any fonts, actually). If you'd like to change fonts with your theme you can either:

• use the local version, or
• download the script generated by the hosted version, and manually change the theme_update() function from, for example:

axis.text = element_text(family = NULL...

to

axis.text = element_text(family = "Arial"...
