Surveys are one of the most important methods of gathering information in studies. ShinyPsych provides a way of including surveys and instructions in an app by simply giving it a text file with the survey.

Common Extensions

For a full description of the layout of the code underlying ShinyPsych - Survey, click here ShinyPsych - Survey Code Description. Here is a brief description of some ways you can easily extend ShinyPsych - Survey:

Check if an entered id is already contained in a dataset

If you conduct your study and want to make sure that some participants who, e.g., participated in an earier similar study, cannot participate, ShinyPsych provides the possibility of loading a dataset of ids and checking whether the entered id matches one from the dataset. To do this, you simply need to extend nextPage() with the check arguments (all arguments of that function that start with check). For a full code example click here

Use different input formats

To use different input formats, you can simply change the input format specified in the type variable of a row in the text file containing the survey information. Click here for a tutorial on how to create such a text file with a template for every input type.
