This advice is almost certainly false! A "t-statistic" can be calculated, but the distribution will not necessarily be student's t nor will the "df" be those of the rse. See, for example, rlm() in MASS, where values of the t-statistic are given without p values. If Brian Ripley says that p values cannot be straightforwardly calculated by pt(), then believe it!
