Can you provide a reproducible example: see, e.g., this site for how to do so:
http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example
Incidentally, I don't believe I can replicate your problem:
x - data.frame(conc = sample(c(100, 1,2,3, 0.005, 0.0005, 0.2),
Can you provide a reproducible example? See, e.g.,
http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example
for information on how to do so.
My entirely unjustified guess is that the NAs appear for combinations
of factor levels that don't exist.

simpleRDA2 is still in the vegan package, but it is not exported.
I.e., the author only intends it for internal use and he doesn't make
it available to end users directly. If you need to get at it, you can
use
