Read data from installed packages

Read data via utils::data and import it into R. The ui includes a "show documentation" button to give info about the datasets.

libData(input, output, session, assignTo = "dt",
  ignoreStyleSheet = TRUE)

libDataUI(id, selected = "datasets")

Arguments

input, output, session	Standard module parameters.
assignTo	A character vector of length one. The symbol to assign the data to in the code.
ignoreStyleSheet	By default, the R documentation pages use a special css sheet for styling. Set this option to FALSE to load this style sheet.
id	The module identifier.
selected	The R package initially selected in the GUI.

Value

A reactive string representing the import of the dataset. for example.

"data('Arthritis', package = 'vcd')\ndt <- Arthritis"

Examples

if (FALSE) {

shinyApp(
  ui = fluidPage(
    libDataUI("import"),
    codeOutput("code"),
    dataTableOutput("table")
  ),
  server = function(input, output, session){
    code <- callModule(libData, "import")
    output$code <- renderCode(code())
    output$table <- renderDataTable({
      eval(parse(text = code()))
      dt
    })
  }
)

}
