#' @param dfa Dataframe. One of the two data frames to be compared
#' @param dfb Dataframe. One of the two data frames to be compared
#' @param argsIn The arguments that were passed to the main dataCompareR function
#' @param keys The keys used to match rows between \code{dfa} and \code{dfb}
#' @param trimChars Boolean. Do we trim characters before comparing?
#' @param mismatches Integer. The max number of mismatches to assess, after which dataCompareR will stop
#' (without producing a dataCompareR object). Designed to improve performance for large datasets.
#' @param roundDigits Integer. If NA, numerics are not rounded before comparison. If /code{roundDigits} is specified, numerics are
#' rounded to /code{roundDigits} decimal places using \link[base]{round}.
#' @return \code{dataCompareRObject} containing details of the comparison
