What is surveydown?


R package that renders Quarto files into surveys


Quarto is a publishing system


Original qmd file



Markdown + R code chunks

---
format: html
title: "HTML Page with R Code"
---

# Hello, World!

This is a simple **HTML** page with *R* code.

```{r}
library(ggplot2)

df <- data.frame(x = rnorm(100))
ggplot(df, aes(x = x)) +
  geom_histogram()
```

Rendered HTML


Original qmd file



Markdown + Python code chunks

---
format: pdf
title: "PDF File with Python Code"
---

# Hello, World!

This is a simple **PDF** file with *Python* code.

```{python}
import matplotlib.pyplot as plt
import numpy as np

data = np.random.normal(0, 1, 100)
plt.hist(data)
plt.show()
```

Use triple-dash marker (---)

to define survey pages

Quarto fences (:::) also OK:

Rendered Survey

Wait a minute…
Quarto renders to static html pages, right?


Shiny to the rescue!


A complete surveydown survey


survey.qmd

A Quarto doc defining the survey content (pages, texts, images, questions, etc).

app.R

An R script defining the survey Shiny app.

Don’t panic!


app.R


library(surveydown)

ui <- sd_ui()
  
server <- function(input, output, session) { 

  sd_server()

} 

shiny::shinyApp(ui = ui, server = server)

app.R


library(surveydown)

ui <- sd_ui()
  
server <- function(input, output, session) { 

  sd_server()

} 

shiny::shinyApp(ui = ui, server = server)

Render survey.qmd as UI

Run the surveydown server

Wait a minute…
How do you store the response data?


PostgreSQL to the rescue!



supabase.com

app.R


library(surveydown)

# sd_db_config()
db <- sd_db_connect()

ui <- sd_ui()
  
server <- function(input, output, session) { 

  sd_server(db)

} 

shiny::shinyApp(ui = ui, server = server)

Store credentials

Connect to the database

Pass connection to sd_server()

survey.qmd

# Conditional Question
sd_question(
  type  = "mc",
  id    = "has_fav_hero",
  label = "Do you have a favorite hero?",
  option = c("Yes" = "yes", "No" = "no")
)

# Target Question
sd_question(
  type  = "text",
  id    = "fav_hero",
  label = "Who is your favorite super hero?"
)

app.R

# Inside server
sd_show_if(
  input$has_fav_hero == "yes" ~ "fav_hero"
)

Condition ~ Target


“If {condition}, then show {target}”

If it works in Shiny,
it works in surveydown.

Embedding an interactive map with leaflet:


surveydown + LLMs
is pretty cool

Generate surveys with LLMs!
