FD package_dbFD error
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. Sarah

Hi everyone,
I am trying to conduct dbFD from the FD package, but it keeps giving me
the same error:
ex1 <- dbFD(sites, traits)
Error in dbFD(sites, traits) :
Different number of species in 'x' and 'a'.
Ab, bb, Ci.... are species names.
I have tried rewriting the species names so many times and ways, but
nothing seems to work. I also checked for blank space but can't seem to
find one. Does anyone have and idea what am I doing wrong?
My data consists of two data frames:
