How much typical French families spent on different types of food in the 1950's.

Description

foodInFrance: How much typical French families spent for food in the 1950's. The families are categorized by social class (manual workers, employees, and executives) and by number of children (from 2 to 5). Interestingly (for historians of economics), at this time, Wine was considered a food.

Usage

data("foodInFrance")

Format

A list containing 2 data frames:

• df.active: the data per se

• supplementary.variables: Additional information long and short names and factors to expliciely identify social class and number of children.

Details

The measurements give the amount in Francs spend by a typical (i.e., average) family on 7 items: Bread, Vegetables, Fruits, Meat, Poultry, Milk, Wine

Because the unit (i.e., Francs spent) is the same all accross the table (and a Franc is a Franc no matter what you buy), this example illustrates the case when the data should not be normalized when performing a PCA.
