sd_skip_if: Define skip conditions for survey pages

Description

This function is used to define conditions under which certain pages in the survey should be skipped. It takes one or more formulas where the left-hand side is the condition and the right-hand side is the target page ID. Only forward skipping is allowed to prevent navigation loops.

Usage

sd_skip_if(...)

Value

A list of parsed conditions, where each element contains the condition and the target page ID.

Arguments

...

One or more formulas defining skip conditions. The left-hand side of each formula should be a condition based on input values, and the right-hand side should be the ID of the page to skip to if the condition is met. Only forward skipping (to pages later in the sequence) is allowed.

Examples

if (interactive()) {
  library(surveydown)

  # Use sd_skip_if() to skip pages based on answers:
  # server <- function(input, output, session) {
  #   sd_skip_if(
  #     input$age < 18 ~ "underage_page",
  #     input$country == "USA" ~ "usa_page",
  #     input$consent == "no" ~ "exit_page"
  #   )
  #   sd_server()
  # }

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