\begin{Section}{\AsIs{\texttt{\bsl{}deqn}}}
1-arg form, centered also in text conversion:
\deqn{
    \theta = (\mu^*, \sigma^2, \rho)
  }{}
2-arg form, where the text version is collapsed before centering
(for the sake of existing Rd files):
\deqn{E = mc^2}{}

With AMS extension (R \eqn{\ge}{} 4.2.2),
where the text version spans more than 3 source lines (5 in fact)
and is thus output as-is in R \eqn{\ge}{} 4.4.0:
\deqn{
    f(x) = \begin{cases}
      0 & \text{if } x < 0, \\
      1 & \text{if } x \ge 0.
    \end{cases}
