sd_reactive function

Create a reactive value that is also stored in survey data

This function creates a reactive value similar to Shiny's reactive() function, but also automatically stores the calculated value in the survey data.

sd_reactive(id, expr, blank_na = TRUE)

Arguments

• id: Character string. The id (name) of the value to be stored in the data.
• expr: An expression that calculates a value based on inputs
• blank_na: Logical. If TRUE, NA values are converted to empty strings. Default is TRUE.

Returns

A reactive expression that can be called like a function

Examples

## Not run:

# In your server function:
product <- sd_reactive("product", {
  input$first_number * input$second_number
})

# Use the reactive value elsewhere
output$result <- renderText({
  paste("The product is:", product())
})

# In your survey.qmd file, display the value:
The product is: `r sd_output("product", type = "value")`.
## End(Not run)
