Description

Example of a data frame from one file with one group of bullet holes.

Usage

data(DFscar17)

Format

A data frame with 10 observations on the following 9 variables.

group

a factor with level 1.

distance

a numerical vector giving the distance to the target.

aim.x

a numerical vector of x-coordinates giving the point of aim.

aim.y

a numerical vector of y-coordinates giving the of point of aim.

point.x

a numerical vector of absolute x-coordinates of bullet holes.

point.y

a numerical vector of absolute y-coordinates of bullet holes.

origin

a factor with level 1. This factor codes from which original output file the data is.

orgser

a factor with level 1.1. This factor results from droplevels(interaction(origin, group)), and codes each separate group across original files. The order of the factor levels is alphabetical.

series

a factor with levels 1. This factor codes each separate group as defined by orgSer, but more conveniently as a number that runs consecutively across original files.

Details

One group of shooting an FN SCAR 17 rifle in .308 Win at 100yd. The measurement unit for coordinates is inch, for distance yards.
