How to Extract Data from a Multiple Column Table with Nested Data

Introduction

This article describes how to go from a multiple column table with more than one statistic and nested data...

...to returning only the cells you need.

Requirements

A multiple-column table with multiple statistics and nested data created by including a Nominal-Multi question as the Row question used in your table. If you're using a table with a nested banner, please see How to Work with Nested Banners and Spans in R Tables.

Method 1 - Point and click

1. Click on the Calculation equal sign.

2. Click on the page to insert a calculation box on the page.

3. While the cursor is blinking (active) in the R CODE box, click on a part of a table that you'd like to extract.

See Bespoke Analyses for examples and a demo of the feature. Note that if you are using point and click with a nested banner, you must use the banner numbers and not the column label, since it is repeated.

Method 2 - By name

1. Select your table

2. Copy the name from Properties > GENERAL > Name

3. Select Calculation > Custom Code.

4. Go to Properties > R CODE in the object inspector.

5. To check the table dimensions, write dimnames(table_name) using the name from step 2 and you will return a list of names for each dimension of your table:

5. Using this definition, we need to add a line in the format of table_name[row_name, column_name, nested_column_name, statistic_name]

Using our example, the code to return just the percentage for females who love Coca-Cola is:

table.gender.brand.attitude["Coca-Cola","Love","Female","Column %"]

To instead return percentages for everyone who likes or loves Coca-Cola is:

table.gender.brand.attitude["Coca-Cola",c("Like","Love"),,"Column %"]

Leaving one of these arguments empty will return all the rows, columns or statistics respectively from the table.

Below the Hate - Love argument has been removed from above so it returns all ratings:

6. OPTIONAL: Add a percentage sign or adjust the number of decimal places via Properties > APPEARANCE > Number format.

Method 3 - By index

1. Select your table

2. Copy the name from Properties > GENERAL > Name

3. Select Calculation > Custom Code.

4. Go to Properties > R CODE in the object inspector.

5. Using the definition from method 1 step 4, we need to add a line in the format of table_name[row_index, column_index, nested_column_index, statistic_index]

Using our example, the code to return the percentage the percentage for females who love Coca-Cola is: table.gender.brand.attitude[1,5,2,1]

To instead return percentages of everyone who likes or loves Coca-Cola is: table.gender.brand.attitude[1,c(4,5),,1]

Alternatively, you can use index ranges, whereby the above can also be written as: table.gender.brand.attitude[1,c(4:5),,1]

You can even reverse this to remove the other ratings instead: table.gender.brand.attitude[1,c(-1:-3,-6),,1]

You can additionally keep only the last cola category by using the NROW argument:

table.gender.brand.attitude[NROW(table.gender.brand.attitude),,,]

6. OPTIONAL: Add a percentage sign or adjust the number of decimal places via Properties > APPEARANCE > Number format.
