queryBuilder is an htmlwidget wrapper for jQuery queryBuilder, a fantastic jQuery plugin to create queries and filters. The htmlwidget generates a dplyr string that can be used to filter a data frame within a shiny app. In addition I’m playing with some experimental features to expand functionality. The first is a way to filter on up/down trend, something that I’ve used in metabolomics studies. The second is a group comparison feature, something that’s achieved by switching out the html on the fly - toggling between a textbox and a combobox. An example of the group comparison filter can be found on codepen and the htmlwidget is hosted on github.
