##
Upper Paleolithic End Scrapers from Castenet A and Ferrassie H, France

### Description

Data on 3000 Upper Paleolithic end scrapers from two sites analyzed by James Sackett (1966) and reanalyzed by Dwight Read (1974 and 2007).

### Usage

`data(EndScrapers)`

### Format

A data frame with 48 observations on the following 6 variables.

`Width`

Width: `Narrow`

, `Wide`

`Sides`

Sides: `Convergent`

, `Parallel`

`Curvature`

End Curvature: `Round`

, `Medium`

, `Shallow`

`Retouched`

Retouching: `Retouched`

, `Unretouched`

`Site`

Site: `Castenet A`

, `Ferrassie H`

`Freq`

Number of end scrapers

### Details

The scrapers are grouped on 5 categorical variables into 48 groups. Sackett's analysis employed Chi square and the examination of residuals. Read used the data to illustrate loglinear modelling (1974, 2007). The data come from Tables IV and VIII (pp 373 and 380) in Sackett's original article
