I have a long equation that I need to break in the R documentation of a package
or it trails off the right hand side of the page. Here's the formula:
\deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 +
\rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+
\rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} +
\rho_{its}\rho_{itu}\rho_{itv}) + \rho_{ius}\rho_{iut}\rho_{iuv} +
\rho_{ivs}\rho_{ivt}\rho_{ivu}]/n_i}
How can I break the formula and optionally indent the second lower piece;
though I'd settle for break it right now?

I don't know if there's a simple answer to this, but you would likely
receive more answers if you made the question easier to answer, by
posting complete code that people could try, not just a fragment. Why
not put together a minimal .Rd file and post that?
Here are two things to try:
Insert \cr where you want a break.
Decide what you want to see in the three formats (HTML, Latex, text) and
manually handle each of them separately.
