)

pickerGroupServer(input, output, session, data, vars)

standard shiny input.

output

standard shiny output.

session

standard shiny session.

data

a data.frame, or an object that can be coerced to data.frame.

vars

character, columns to use to create filters, must correspond to variables listed in params.

Value

a reactive function containing data filtered.

Examples

if (interactive()) {

library(shiny)
library(shinyWidgets)


data("mpg", package = "ggplot2")


ui <- fluidPage(
  fluidRow(
    column(
      width = 10, offset = 1,
      tags$h3("Filter data with picker group"),
      panel(
        pickerGroupUI(
          id = "my-filters",
          params = list(
            manufacturer = list(inputId = "manufacturer", label = "Manufacturer:"),
            model = list(inputId = "model", label = "Model:"),
            trans = list(inputId = "trans", label = "Trans:"),
            class = list(inputId = "class", label = "Class:")
          )
        ), status = "primary"
      ),
      DT::dataTableOutput(outputId = "table")
    )
  )
)

server <- function(input, output, session) {
  res_mod <- callModule(
    module = pickerGroupServer,
    id = "my-filters",
    data = mpg,
    vars = c("manufacturer", "model", "trans", "class")
  )
  output$table <- DT::renderDataTable(res_mod())
}

shinyApp(ui, server)

}
