No. Whereas I partly agree that it's Ross ``fault'' trying to use too smart LaTex (and using outdated \bf instead of \mathbf), ;-)

The bug is really there, since we are talking about the Rd "language", not LaTeX, an in Rd, \eqn and \deqn are defined to have either one or two arguments -- where Ross used the 2-argument version correctly (in principle at least) --> See the manual "Writing R Extensions".
