Documented in hitlogic

#' Hit Logic (Discrete)
#' Wrapper that computes discrete hitcalls for a provided concRespCore dataframe.
#' @param indf Dataframe similar to concRespCore input Must contain "conc" and "resp"
#'   columns if xs and ys are not provided. Must contain "cutoff" and "bmad_factor"
#'   columns if newbmad is not NULL. Must contain "top" and "ac50" columns. "conc"
#'   and "resp" entries should be a single string with values separated by |.
#' @param newbmad (Deprecated) New number of bmads to use for the cutoff.
#' @param xs List of concentration vectors that can be provided for speed.
#' @param ys List of response vectors that can be provided for speed.
#' @param newcutoff Vector of new cutoff values to use. Length should be equal
#'   to rows in indf.
#' @return Vector of hitcalls with length equal to number of rows in indf.
