qmjdata: Data for the qmj package

#' Financial statements of all companies in the Russell 3000 index 
#' for the past four years
#'
#' A data frame containing all annual financial statements (balancesheets,
#' cashflows, and income statements) for the past four years if available.
#' For a description of the Russell 3000 index, as well as why it was used
#' for this package, see \code{\link{companies}}. Last updated 2016/01/06.
#' 
#' Some companies may store "weird" data, such as having information solely 
#' for the years 1997-2001, or by having multiple annual reports within the
#' same year (such as one report being filed in March of 2013, and another 
#' filed in December of 2013). In the case of companies reporting multiple 
#' annual data from the same year, the years of their reports are suffixed 
#' with their order. For example, GOOG may have data from 2013.1, 2013.2, 
#' 2012.3, 2011.4. This means Google's most recent data set is from 
#' 2013 (2013.1), another data set was published in 2013 (2013.2), and the 
#' remaining years are also suffixed for convenience.
#' 
#' The main purpose of financials is to provide key information for each 
#' company in order to calculate each of the quality component scores 
#' (profitability, growth, safety, and payouts). For every ticker in the 
#' \code{\link{companies}} data set, financials will try to store the most 
#' recent four years of annual data, though this may vary based on 
#' availability.
