Combined bullet hole data

Description

Example of a combined data frame from several original files, each with one group.

Usage

data(DFsavage)

Format

A data frame with 180 observations on the following 10 variables.

point.x

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

point.y

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

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.

distance

a numerical vector giving the distance to the target.

group

a factor with level 1. This is the original Group variable as defined by OnTarget PC/TDS.

bullet

a character vector describing the bullet type.

origin

a factor with levels 1 ... 9. This factor codes from which original output file the data is.

orgser

a factor with levels 1.1 ... 9.1. 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 ... 9. 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

Several groups of shooting a Savage 12 FT/R rifle in .308 Win at distances from 100 to 300m. The measurement unit for coordinates is mm, for distance meters. Shots 1-5 in series 4, and shots 1-3 in series 7 moved the scope.
This data frame is like those returned by readDataOT1, readDataOT2, or readDataMisc with option combine=TRUE.
