gun
Speed of Firing Naval Guns

### Description

The gun data frame, a design object, has 36 rows representing runs of a team of 3 men loading and firing naval guns attempting to get off as many rounds per minute as possible. The three predictor variables (columns) specify the team and the physique of the men on it and the loading method used; the outcome variable is the rounds fired per minute.

### Arguments

Method | factor giving one of two methods for loading rounds into Naval guns. Levels are M1 and M2 .
Physique | an ordered factor giving the physique of the men: S for slight, A for average, and H for heavy.
Team | factor with levels T1 , T2 or T3 . In fact there are nine teams, three of each physique, i.e. a slight T1 , an average T1 , and a heavy T1 , etc.
Rounds | numeric vector giving the number of rounds per minute fired by a team.
