You can also create a reset button by assigning NULL to your reactive values object.

See this RStudio Shiny article on Using Action Buttons: http://shiny.rstudio.com/articles/action-buttons.html. Specifically, read the sections titled Pattern 4 - Reset buttons and Pattern 5 - Reset on tab change. Examples (including code) are provided in the article.

The article provides solutions that don't require additional packages if that's a concern.
