How to Hide an Output with a Small Sample Size Using a Calculation

Introduction

This article describes how to go from a table...

...to an output that displays a custom message when the sample size is too small.

Requirements

A table with a sample size statistic showing, such as Column Sample Size or Sample Size.

Method

1. Select your table.

2. Go to Properties > GENERAL > Name and copy the object name.

3. Select Calculation > Custom Code.

4. In the object inspector, go to Properties > R CODE.

5. Reference the name of the table from step 2 and the cell (row 1, column 2) where the sample size figure is: n = sample.table[1, 2] .

6. Set the minimum sample threshold: min.sample = 40.

7. Paste in the rest of the code to display a transparent box with a specific message when the sample is below this threshold:

html = if (n >= min.sample) '' else '<!DOCTYPE html>
<html>
<head>
<style>
body { background-color: white; }
</style>
</head>
<body>
Sample size is too small to show results
</body>
</html>'
rhtmlMetro::Box(html, text.as.html = TRUE)

8. Resize the output to cover whatever you wish to disappear.
