Phillip,
You approach to using factors misses an important consideration; the
class that was observed in the full dataset should not disappear just
because you subsetted the data in some manner. Also, `droplevels()` is
a useful function to call on a factor or data frame if subsetting
produces

Kendra,
Something is wrong in X or P; find out what the foreign function call is
and then you may be able to track down the offending data problem.
Maybe a logarithm somewhere? This is probably

Kendra,
I wonder if the problem is a factor level with no observations. One of the
frustrating things about factors (class variables) in R is that the list of
levels is stored separately from the data. This can cause all sorts of
problems if you create the factor, then subset the data, and
Thanks, I think it was the odd variable that was named f.env$zone I removed
that column and suddenly things started working

Maybe a logarithm somewhere? This is probably not much help; I don't
have much experience with envfit.

I'm running a bunch of NMS with vectors fitted (slicing and dicing a large
dataset in different ways). I'm suddenly getting an error from envfit
f.bSBS.org.fit-envfit(f.bSBS.org.nms, f.bSBS.org.env, permutations=999,
na.rm=TRUE)
Error in vectorfit(X, P, permutations, strata, choices, w = w,
