Women daily nutrient intake


The nutrient data frame consists of quintuples consisting of four day measurements for intake of calcium, iron, protein, vitamin A and C from women aged 25 to 50 in the United States as part of the "Continuing Survey of Food Intakes of Individuals" program. The processed data has 737 measurements from a cohort study of the United States Department of Agriculture (USDA) and it is available online from the University of Pennsylvania repository.


This data frame contains the following columns:


A numeric vector containing the identification of the participant.


A numeric vector containing measured calcium.


A numeric vector containing iron measurements.


A numeric vector containing protein measurements.


A numeric vector containing vitamin A measurements.


A numeric vector containing vitamin C measurements.


The survey data was processed by Dr. Andrew Wiesner for a course on multivariate statistics at The Pennsylvania State University.
