[R] FD package_dbFD error

[Sarah Goslee]

Hi,

While Bert is right that this would be a good question for
r-sig-ecology, I think you might have made a very simple-to-fix
mistake:

According to https://www.rdocumentation.org/packages/FD/versions/1.0-12/topics/dbFD
if you don't name the arguments, traits should come BEFORE sites.

If that doesn't help, take a look at the site and trait data frames
used in the examples and see if you can figure out where you went
wrong. If you can't, then try r-sig-ecology.
