Correlation between package output
Hello
I'm currently using the dbFD function of the FD package and i'm having some
things that I can't do.
Is there any way to check the relations between dbFD indexes?
Function cor for example? I can't manage to put the informations correctly
dbFD function gives a lot of output (indexes - nbsp, sing.sp, FRic, FEve,
FD...

dbFD computing distinct species wrong?
Hi everyone,
I am working with the dbFD function of the FD package, and there's something
funny happening with the value of sing.sp in the output. Basically, I have
a species-function matrix and a community matrix. One site in particular
has 6 species, 4 of which have identical functional coding. I thus expect
nbsp = 6 and sing.s...

Problem with dbFD function in FD library
...?calc.Frich= F? and gives the Feve, Fdis, RaoQ and CWM values
for my data. When I run the function with ?calc.Frich=T?, I see the warning
that I wrote below and no one of the values are calculated.
Could you please tell me how can I fix this problem and have the FRic value
for my data?
Func.div?dbFD ( trait_data, abundance_data, calc.FRic = T, corr="cailliez",
w.abun = T, CWM.type = "all" )
FRic: Dimensionality reduction was required. The last PCoA axis (out of 6
in total) was removed.
FRic: Quality of the reduced-space representation = 0.9402678

FD: R package to measure functional diversity indices
...age is intended for ecologists interested in functional
diversity (FD). It measures different functional diversity indices
from multiple traits (any type of traits). The first version of FD
(1.0-0) is now available on CRAN:
http://cran.r-project.org/web/packages/FD/
The main functions of FD are:
dbFD: Compute different multidimensional FD indices
gowdis: Gower dissimilarity, including options for variable weights,
asymetric binary variables, and implementing Podani's (1999) extension
to ordinal variables
fdisp: Functional dispersion
functcomp: Functional composition (community-weighted m...
