Very commonly with survey data, we want to turn a categorical array into a "top box" (or "top 2 box", etc) question. Or perhaps you've set up a Yes/No question as a Categorical Array, and you're really only interested in the "Yes" response (that is the same thing in essence as a "top box").

In data processing, this is known as dichotomizing the array, because you're collapsing the data into a binary Yes/No, or 1/0, situation, and thus producing a multiple response variable.

The code works as follows:

• Open this R script (in R Studio): MR Builder v1.R
• Login and load up your dataset
• The code produces a CSV file in your working directory.
• The CSV file shows all the categorical arrays in the dataset. You fill in the CSV and resave.
• Run the rest of the code

How to fill in the CSV

The CSV file will display all the categorical arrays in the dataset.

• You put an "x" in all the boxes that you want to count in the multiple response question. 
• You also have the opportunity to rename at this point a multiple response question that's about to be created.
• You don't need to fill in an "x" for every variable displayed, only the ones that you want top boxes for.

Further notes:

• At this time of writing this article, the CSV also displays numeric and text variables - this will be corrected shortly.
• A worked example will be placed here very soon.
• Be sure to overwrite the CSV in your working directory (if using Numbers on a Mac, be sure to "export as a CSV", rather than just save).
