DFlandy04: Combined bullet hole data

Description

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

Usage

data(DFlandy04)

Arguments

Format

A data frame with 100 observations on the following 12 variables.

group: a numerical vector with group numbers 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.
ammunition: a character vector giving ammunition and lot number.
velocity: a numerical vector of chronograph readings in ft/s.
file: a character vector with the original file name.
groupVerb: a character vector designating the group by combining the original file name and ammunition.
series: a character vector that codes each separate group in an alternative way.
seriesNum: like series but numeric.
distance.unit: Measurement unit distance to target
point.unit: Measurement unit (x,y)-coordinates

Details

6 groups with 25 shots each (groups 1-5) or 50 shots (group 6) of .22LR shot at a distance of 50yd. The measurement unit for coordinates is inch, for distance yards.
Groups 1-3 shot with a Stiller Copperhead action with Shilen Octagon Barrel. Group 4-5 shot with a Baity Falcon action with Shilen Ratchet Barrel. Group 6 shot with a Stiller 2500X action with Shilen Octagon Barrel.
This data frame is like those returned by readDataOT1, readDataOT2, or readDataMisc with option combine=TRUE.
