Hi Nathan,
sorry about the delay in responding.
The test of whether all of the bootstrap values are equal is in the wrong
place. I will correct it in the next release. Meanwhile, I think the
simplest solution is to fix(boot.ci) and move the line
if (const(t, min(1e-08, mean(t)/1e+06)))

Some bootstrap resamples are giving infinite results for the first
component of the statistic. That can certainly happen, given the censoring
pattern. Here is one such bootstrap resample

The function anosim() in vegan package or sample() in base may be of help to
