#' @param <% if (exists("icd9ShortName")) cat(icd9ShortName) else cat("icd9Short") %>
#'   is a character vector of ICD-9 codes. If fewer than five
#'   characters is given in a code, then the digits are greedily assigned to
#'   hundreds, then tens, then units, before the decimal parts. E.g., \code{10}
#'   becomes \code{010}, not \code{0010} or \code{00010}.
