How to Hide an Output with a Small Sample Size Using an R Error

Introduction

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

...to an output that displays the table percentages when over a certain sample size, otherwise it shows a custom error message. 

Requirements

A table with a sample size statistic showing, such as Column Sample Size or Sample Size. In this example we are using a crosstab with Column % and Column 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: tab = table.exercise.frequency

6. Paste in the rest of the code to display an error message with a specific message when the sample is below a specified threshold:

data = tab[,,"Column %"]
sample.size = max(tab[,,"Column Sample Size"])
if (sample.size < 70)
stop("The sample size is too small for valid analysis.")
data
