error message in package "FD", function dbFD ()

[snip]

identical(row.names(x), row.names(t(a)))

I'm guess this will yield "FALSE" (although they look identical in your
output below).

If FALSE, then you just need to confirm that the species names are
actually identical (is there a space at the end of one?, or manually
re-type to confirm, etc., etc.).

Good luck,
Phil

Dear R community,



I  have some trouble with the dbFD function in the FD package.

str(a)

'data.frame':    150 obs. of  48 variables:

str(x)

'data.frame':    48 obs. of  9 variables:



ex1 <- dbFD(x,a)

Error in dbFD(x, a) :

  Species labels in 'x' and 'a' need to be identical and ordered

alphabetically (or simply in the same order).

I have checked multiple time the data set but this message keeps on

appearing. The names of the species are identical in both data.frames.

I was wondering if you could help me by giving me an example of an excel

trait and species matrix table to upload for this package. Below is a
snapshop of my data. I have also checked that there are no NA's problems
and that there is no species abundance = 0 or no community with 0 species.

Thank you for any advice!

Best

Laura
