No. A counter-example is -binomial()-. But the converse appears to be
almost true.
Whenever you want to specify an integer df, the argument in question is
called n, n1, or n2.

Is n in the probability functions always df? Like in ttail(n,t)?
Several of the functions are explicit with this, several are not. I've
always assumed it was df.
