Output Function for Displaying reactive objects and values

Usage

sd_output(
  id,
  type = NULL,
  width = "100%",
  display = "text",
  inline = TRUE,
  wrapper = NULL,
  ...
)

Arguments

id: Character string. A unique identifier for the output element.
type: Character string. Specifies the type of output corresponding with the question id. Can be "question", "value", "label_option", "label_question", or NULL. If "question", it will display a question defined in the server. If "value", it will display the value of question id selected by the respondent. If "label_option", it will display the label of the option for question id selected by the respondent. If "label_question", it will display the label argument value for question id. Finally, if NULL, the function behaves like shiny::uiOutput().
width: Character string. The width of the UI element. Defaults to "100%".
display: Character string. Specifies the display type for "value" outputs. Can be "text", "verbatim", or "ui". Only used when type = "value".
inline: Logical. Whether to render the output inline. Defaults to TRUE.
wrapper: Function. A function to wrap the output. Only used when type = "value".
...: Additional arguments passed to the underlying 'shiny' functions or the wrapper function.

Value

A 'shiny' UI element, the type of which depends on the input parameters.

Details

The function behaves differently based on the type parameter:

If type is NULL, it acts like shiny::uiOutput().
If type is "question", it creates a placeholder for a reactive survey question.
If type is "value", it creates an output to display the value of a survey question, with the display style determined by the display parameter.

Examples

if (interactive()) {
  library(surveydown)

  # Use sd_output() to display reactive questions or values:
  # First, define something in server of app.R:
  # server <- function(input, output, session) {
  #   completion_code <- sd_completion_code(10)
  #   sd_store_value(completion_code)
  #   sd_server()
  # }

  # Then, display in R chunks of survey.qmd:
  # Your code is: `r sd_output("completion_code", type = 'value')`

  # Find a working directory and start from a template:
  sd_create_survey(template = "reactive_questions")
  # This creates survey.qmd and app.R - launch the survey using app.R
