concrete: Concrete Compressive Strength Data

In fastR: Data sets and utilities for Foundations and Applications of Statistics by R Pruim

Description

These data were collected by I-Cheng Yeh to determine how the compressive strength of concrete is related to its ingredients (cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, and fine aggregate) and age.

Usage

data(concreteAll); data(concrete28)

Format

concreteAll is a data frame with the following 9 variables.

cement

amount of cement (kg/m^3)

slag

amount of blast furnace slag (kg/m^3)

ash

amount of fly ash(kg/m^3)

water

amount of water (kg/m^3)

superP

amount of superplasticizer (kg/m^3)

coarseAg

amount of coarse aggregate (kg/m^3)

fineAg

amount of fine aggregate (kg/m^3)

age

age of concrete in days

strength

compressive strength measured in MPa

concrete28 is a subset of concreteAll.

Source

Data were obtained from the Machine Learning Repository (http://archive.ics.uci.edu/ml/) where they were deposited by I-Cheng Yeh ([e-mail]) who retains the copyright for these data.

The 'mosaic' package masks several functions from core packages in order to add 
additional features.  The original behavior of these functions should not be affected by this.

Note: If you use the Matrix package, be sure to load it BEFORE loading mosaic.
