\description{
This dataset contains records of the careers of officers of the line in the
United States Navy who became midshipmen between 1798 and 1849. It lists the
dates at which officers were promoted to the ranks of midshipment,
lieutenant, master commandament, and captain.
}
\section{Variables}{


  \itemize{

  \item \code{id}: A unique numeric identifier for each officer.

  \item \code{name}: Name of the officer.

  \item \code{generation}: A numeric value to represent a judgment about the
  generations within the officer corp of the U.S. Navy. First generation
  officers entered the service before 1801, as a rank higher than midshipman.
  Second generation officers entered the service before the Peace
  Establishment Act (or by the end of 1801), but as midshipman. Thus, they
  essentially became adults in the service, and they learned their craft from
  the first generation. Third generation officers entered the service as
  midshipmen after the Peace Establishment Act but before the end of the War
  of 1812. Those officers in this generation who became captain rose to that
  rank in the 1830s and '40s. Fourth generation officers entered the service
  after the War of 1812 had ended. These officers saw almost no wartime
  service, and many of the ones who achieved captain found themselves having
  to decide whether to serve in the Union or the Confederacy during the Civil
  War.

  \item \code{rank}: The ranks which officers obtained, including
  \code{midshipman}, \code{lieutenant}, \code{master_commandant}, and
  \code{captain}. Also included are the dates some officers
  \code{left_service}.

  \item \code{date}: The date as a character string on which an officer
  attained the associated rank. }
