DFcciHV {shotGroups}

Combined bullet hole data

Description

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

Usage

data(DFcciHV)

Format

A data frame with 40 observations on the following 9 variables.

group

a factor with levels 1 2.

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 levels 1. This factor codes from which original output file the data is.

orgser

a factor with levels 1.1 1.2. 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 2. This factor codes each separate group as defined by orgser, but more conveniently as a number that runs consecutively across original files.

distance.unit

Measurement unit distance to target

point.unit

Measurement unit (x,y)-coordinates

Details

Two groups of shooting a PWS T3 rifle in .22LR at 100yd. The measurement unit for coordinates is inch, for distance yards.
This data frame is like those returned by readDataOT1, readDataOT2, or readDataMisc with option combine=TRUE.
