Easily Create and Deploy Surveys from R
By Jonathan Trattner in R Shiny packages shinysurveys
July 2, 2019
{shinysurveys} provides easy-to-use, minimalistic code for creating and deploying surveys in Shiny. Originally inspired by Dean Attali’s shinyforms, this package provides a framework for robust surveys, similar to Google Forms, in R with Shiny.

Demos
A survey made with our package might look like this:
You can run a demo survey with the function shinysurveys::demo_survey()
.
Getting Started
Aside from demo_survey()
, {shinysurveys} exports two functions: surveyOutput()
and renderSurvey()
. The former goes in the UI portion of a Shiny app, and the latter goes in the server portion. To create a survey, you can build a data frame with your questions. The following columns are required.
- question: The question to be asked.
- option: A possible response to the question. In multiple choice questions, for example, this would be the possible answers. For questions without discrete answers, such as a numeric input, this would be the default option shown on the input. For text inputs, it is the placeholder value.
- input_type: What type of response is expected? Currently supported types include
numeric
,mc
for multiple choice,text
,select
, andy/n
for yes/no questions. - input_id: The id for Shiny inputs.
- dependence: Does this question (row) depend on another? That is, should it only appear if a different question has a specific value? This column contains the input_id of whatever question this one depends upon.
- dependence_value: This column contains the specific value that the dependence question must take for this question (row) to be shown.
- required: logical TRUE/FALSE signifying if a question is required. Surveys can only be submitted when all required questions are answered.
Our demo survey can be created as follows:
library(shiny)
library(shinysurveys)
df <- data.frame(question = "What is your favorite food?",
option = "Your Answer",
input_type = "text",
input_id = "favorite_food",
dependence = NA,
dependence_value = NA,
required = F)
ui <- fluidPage(
surveyOutput(df = df,
survey_title = "Hello, World!",
survey_description = "Welcome! This is a demo survey showing off the {shinysurveys} package.")
)
server <- function(input, output, session) {
renderSurvey(df = df)
observeEvent(input$submit, {
showModal(modalDialog(
title = "Congrats, you completed your first shinysurvey!",
"You can customize what actions happen when a user finishes a survey using input$submit."
))
})
}
shinyApp(ui, server)
Advanced Surveys
-
Dependencies can be added so a specific question will appear based on a participant’s answer to preceding questions. The
dependence
column takes an input_id of a preceding question and, if the participant answers with the value independence_value
, the new question will be shown. -
Required questions can be specified by adding the value
TRUE
to therequired
column. If a required question is not answered, the user will not be able to submit their responses. -
URL-based user tracking functionality lets you keep track of participants easily and systematically. If you deploy your survey on shinyapps.io, or run it locally in a browser, you can add a URL parameter after the backslash as follows:
?user_id=UNIQUE_ID
. A live demo can be found here: https://jdtrat-apps.shinyapps.io/shinysurveys_user_tracking/?user_id=hadley
