I have an error with fisher.alpha from the vegan package.

> fisher.alpha(data[[1]])
Error in nlm(Dev.logseries, n.r = n.r, p = p, N = N, hessian =
TRUE, ...) :
  missing value in parameter

I am trying to find fisher alpha for a list of 100 data frames, and I
tried it on individual data frames in the list, which gave me the
error above.
I have every data frame in the same format as the example data BCI,
species as column names and quadrats as row names.

Can anyone explain what the error is about? Thanks a lot.
