The problem is that % in Rd is different than % in LaTeX: it causes a
break. So the comment you have at the end of the first arg to \deqn
causes the parser to think you have a one argument version of it,
followed by an unnecessarily braced bit of text.
To fix it, change the two lines
{\mbox{Beta}(\theta(1-p),\theta p)}}%
{p(x) = %
to
{\mbox{Beta}(\theta(1-p),\theta p)}%
}{p(x) = %
