In nclSLR: The nclSLR package.

Description

This data set contains statistics, in arrests per 100,000 residents for assault, murder, and rape in each of the 50 US states in 1973. Also given is the percent of the population living in urban areas and the Census Bureau-designated region

Usage

data(USArrests, package="nclSLR")

Value

A data frame with 50 observations on 5 variables.:

Murder

Murder arrests (per 100,000); a numeric vector.

Assault

Assault arrests (per 100,000); a numeric vector.

UrbanPop

Percent urban population; a numeric vector.

Rape

Rape arrests (per 100,000); a numeric vector.

Note

USArrests contains the data as in McNeil's monograph. For the UrbanPop percentages, a review of the table (No. 21) in the Statistical Abstracts 1975 reveals a transcription error for Maryland (and that McNeil used the same “round to even” rule that R's round() uses), as found by Daniel S Coven (Arizona).
