abstract: 'An implementation of an S3 class based on a double vector for storing and
  displaying precision teaching measures, representing a growing or a decaying (multiplicative)
  change between two frequencies. The main format method allows researchers to display
  measures (including data.frame) that respect the established conventions in the
  precision teaching community (i.e., prefixed multiplication or division symbol,
  displayed number <= 1). Basic multiplication and division methods are allowed and
  other useful functions are provided for creating, converting or inverting precision
  teaching measures. For more details, see Pennypacker, Gutierrez and Lindsley (2003,
  ISBN: 1-881317-13-7).'
