#' Length Weight Data

#' This is a data set of extracted specimen data from RACEBASE 
#' The example data set included in this package is called lwdata 
#' and is specimen data (length and weight specimens) for all 
#' species where this data was collected on RACE bottom trawl 
#' surveys. The data was initially extracted from RACEBASE 
#' tables (including HAUL, SPECIMEN, SPECIES and STRATA tables). 
#'
