Make your R Shiny buttons look better with these 3 tips #shorts #rstats #datascience

1. Use a CSS Bootstrap class

As the CSS Boostrap library is a dependency of Shiny, you can simply add a Bootstrap class inside the actionButton() function using the class argument, such as “btn-primary”, “btn-info”, “btn-danger” or “btn-success”. They classes will change the color of the button. You can also easily change the size of the button by adding “btn-lg” or “btn-sm”.

2. Add a Font Awesome Icon

You can also add an icon from the library “Font Awesome” or “Glyphicon” using the icon() function, for example the icons “download” or “refresh”.

3. Change the theme of your R Shiny app

You can change the default color palette by using the {bslib} R package to change your R Shiny theme. You can choose for example the Bootswatch themes “cerulean”, “minth” or “united”.

You can even create you own palette by customizing the colors in the bs_theme() function, for example by making the success button of color “lightgreen” or the danger the color “coral”.
