Create a Shiny App for Dumbbell Plots

This function generates a Shiny application for interactive dumbbell plots. The app features a Data Import section for uploading data, a Data Table for filtering the active dataset, and a Plot area for configuring and displaying an interactive dumbbell plot.

Usage

dumbbellPlotApp(data_list = NULL)

Arguments

data_list: An optional named list of data frames. If NULL (the default), list("school_earnings" = example_school_earnings) is used as example data.

Value

A Shiny app object.

Details

When data_list is not provided (or NULL), the app launches with example_school_earnings as an example dataset. Uploaded data files are added to the available datasets and can be selected for plotting. If an uploaded file shares a name with an existing dataset, the existing one is overwritten with a warning.

This is a convenience wrapper around createModuleApp().

Examples

library(VizModules)
# Launch with default example data:
app <- dumbbellPlotApp()
if (interactive()) runApp(app)

# Launch with custom data:
data <- data.frame(
    School = c("MIT", "Stanford", "Harvard"),
    Women = c(94, 96, 112),
    Men = c(152, 151, 165),
    Group = c("A", "B", "A")
)
app2 <- dumbbellPlotApp(list("School Earnings" = data))
if (interactive()) runApp(app2)
