#' @details
#' This data set includes votes for each of the U.S. House of Representatives
#' Congressmen on the 16 key votes identified by the CQA. The CQA lists nine
#' different types of votes: voted for, paired for, and announced for (these
#' three simplified to yea), voted against, paired against, and announced
#' against (these three simplified to nay), voted present, voted present to
#' avoid conflict of interest, and did not vote or otherwise make a position
#' known (these three simplified to an unknown disposition).
#'
#' NOTE: It is important to recognize that "?" (now coded as "NA" in ucimlr
#' package) in this database does not mean that the value of the attribute is
#' unknown. It means simply, that the value is not "yea" or "nay".
