textOutput {tabler}R Documentation

Text Output Placeholder

Description

Places a <span> in the UI whose content is updated by renderText in the server.

Places a <pre> in the UI for monospace/printed output.

Places a tag (by default a <div>) whose inner HTML is replaced wholesale by renderUI output.

Returns a character string that is HTML-escaped and injected as the inner HTML of the matching textOutput placeholder.

Captures the print() representation of the result and shows it verbatim (HTML-escaped).

Returns an HTML tag tree that replaces the inner HTML of the matching uiOutput placeholder.

Places a <div> in the UI whose content is replaced by a base-R plot rendered server-side via renderPlot.

Evaluates expr inside an SVG graphics device, and injects the resulting inline SVG into the matching plotOutput placeholder. Works with base-R graphics, tinyplot, ggplot2, lattice, and any other graphics system that honours the active device.

Places a <div> in the UI whose content is replaced by an htmlwidget (e.g. from d3po, leaflet, plotly) rendered by a matching server-side call. The widget is served inside a sandboxed <iframe> so its own JS/CSS cannot conflict with the page.

Generic render function for any htmlwidgets-based widget. Captures the expression without evaluating it and stores the calling environment, so tablerApp can evaluate it inside a reactive context without requiring a live Shiny session. Reactive values referenced inside expr are tracked automatically.

Assigned to output$id, serves a file for download when the browser requests the matching downloadButton's link, similar to shiny::downloadHandler(). Unlike other outputs, the file is generated fresh (not cached/pushed) each time it is requested.

Creates a link that triggers a file download from the matching downloadHandler, similar to shiny::downloadButton()/shiny::downloadLink().

Usage

textOutput(outputId, inline = FALSE)

verbatimTextOutput(outputId)

uiOutput(outputId, container = div, ...)

htmlOutput(outputId, container = div, ...)

renderText(expr)

renderPrint(expr)

renderUI(expr)

plotOutput(outputId, width = "100%", height = "400px")

renderPlot(expr, width = 800, height = 400)

widgetOutput(outputId, width = "100%", height = "400px")

renderWidget(expr)

downloadHandler(filename, content, contentType = NULL)

downloadButton(
  outputId,
  label = "Download",
  class = "btn-primary",
  icon = "download",
  ...
)

downloadLink(outputId, label = "Download", class = NULL, icon = NULL, ...)

Arguments

outputId The output identifier (must match the server-side downloadHandler assigned to output[[outputId]]).
inline If TRUE, use <span>; otherwise <div>.
container A tag-building function used to create the placeholder element, e.g. tags$h1. Defaults to div.
... Additional HTML attributes.
expr Expression that returns an htmlwidget object (e.g. d3po(...), leaflet(...)).
width CSS width string (default "100%").
height CSS height string (default "400px").
filename A string, or a zero-argument function returning a string, giving the filename offered to the browser (e.g. "data.csv").
content A one-argument function function(file) {...} that writes the file's contents to the path given by file.
contentType Optional MIME type string. If NULL (default), it is guessed from the filename's extension.
label Link/button text.
class Additional CSS classes (default "btn-primary" for downloadButton, none for downloadLink).
icon Optional icon name to prepend.

Details

Package authors who ship their own render_*() helpers can make them tabler-compatible by attaching the same two attributes: 

  attr(fn, "tabler_expr") <- substitute(expr)
  attr(fn, "tabler_env")  <- parent.frame()

This is exactly what render_d3po() in d3po already does.
