Automatically Combine Categories - By Geography - Europe - To Communities

  • Updated
Follow
The features in Automatically Combine Categories > By Geography allow you to combine geographic data, such as postcodes or city names, into categories, such as states or regions. The features are organized in submenus based on region of the world and desired output categories. Entries that are not found in the regional database are assigned a value of "Other" in the created output variable.

This feature can be used to map an input variable containing European postcodes or place names (e.g. cities and towns) to a new variable containing the corresponding provinces.

Example

In this table we have postal codes from france in the left column, and the result of transforming these to the corresponding communities in the right column:

Usage

In Q:

  1. Select a table showing the question you want to use to create combined categories, or a single variable in the Variables and Questions tab.
  2. Select the region the data comes from and the desired output type from Automate > Browse Online Library > Create New Variables > Automatically Combine Categories > By Geography > Europe > To Communities.
  3. To change how the categories are combined:
    1. Select the new variable or question in the Variables and Questions tab.
    2. Right-click and select Edit R Variable.
    3. Choose the desired options in the Inputs section on the right.
    4. Click Update R Variable.

n Displayr:

  1. Select the variable you want to aggregate (for example, postcode) and click the plus sign mceclip4.png to the right of the variable
  2. From the Insert Variable(s) menu, select Ready Made New Variables > Automatically Combine Categories > By Geography > Europe > To Communities. 
  3. To change how categories are combined (for example, you might decide that the counties aren't very useful and you would prefer regions instead)
    1. Select the new variable you created from the Data Sets tree 
    2. In Object Inspector, select Inputs > Automatically Combine Categories > Output geographic type menu,
    3. Change the selection to option.

Note: If some entries in your input data could refer to any of several possible locations with the same name in the region, you will be shown additional prompts where you can supply a supplementary variable (e.g. containing state/provinces names for each place) to disambiguate the entries to their correct location. In some instances, you may see this prompt when your input data is actually a different type, such as counties or states, in which case you can select the proper type using the prompts.

Options

Variable The input variable containing geographic data to be combined into categories.

Combine by Use this control to toggle between the other methods for combining categories in the the Automatically Combine Categories menu such as By Value > Tidy Categories.

World region The geographic region that the input data/variable comes from.

Input data type The type of data/geographic unit, such as States, Postcodes, or Place (city, town, etc.), that the input variable contains.

Output geographic type The desired geographic unit to combine the input data into. Must be a larger type than Input data type; e.g. it is possible to map U.S. counties to U.S. states, but not the other way around.

Check spelling If this option is selected then approximate matching is performed using the Levenshtein distance, instead of requiring exact matching when looking up the input data values in the regional database.

Check neighboring region Select this option if the input data comes from more than one region than the one specified by World region. For example, with World region set to USA and this option selected, matches for the input data will also be looked for within Canada.

Supplementary variable Only shown when Input data type is Place (city, town, etc.). Use this dropbox to supply an additional variable with geographic info (such as state or region) to disambiguate place names in the input data that could represent multiple distinct locations in the region.
