Jefferson,
With your missing relocation data you are now faced with broad decisions
about how to work with these trajectories, but you are not alone with this
problem -- most projects that track animals suffer this problem. I would
start by asking what biological questions you are trying to answer. From
there you may consider your options. As you seek to generate a regular
trjecotries, you may consider the use of a correlated random walk algorithms
(http://cran.r-project.org/web/packages/crawl), which will require
considerable thought on how to tune these algorithms to the unquique
problems of your tracking dataset.
