Hi again
Is there any way to check the relations between dbFD indexes?
Function cor for example? I can't manage to put the informations correctly
I want to see the relationships between the dbFD output (nbsp, sing.sp,
FRic, FEve, FDiv, FDis and RaoQ)
How should I type it?
Thank you

The values in a$x do look numeric. What do you get from:
class(a$x)
If the result is "factor", as it was for your ft$trait3 variable (and
I hope that a$x is the same variable with a different name), then at
least one of those values must have been read in as non-numeric. The
possible reasons for
That code doesn't show what a$x IS, just what comes out after you force things.
The fact that you felt compelled to apply those functions just makes it seem
more likely that Jim is onto something. The output of
str( a$x )
would show what kind of data it is, and
dput( a$x )
would let us put th
Hey Jim
they are all numeric as you can see
as.numeric(as.character(a$x))

Hi Fabio,
What has probably happened is that ft$trait3 looks like numbers but
when it was read in at least one value could not be read as a number.
The default behavior in R is to transform the variable into a factor:
testcase<-read.table(text="1 2 3 4
1 2 3 4
1 2 B 4")
> testcase
V1 V2 V3 V4

Hi Fabio,
You should write:
class(...)
where ... is the same as what you would type to have the variable
displayed on the console. Looking at your earlier message, it might
be:
x$trait3
so try:
class(x$trait3)

i just called trait3 to my variable.
Is this what i'm suppose to wright? class(trait3), or class
(my_trait3_variable?
both give error

Hi Fabio,
It is possible that your remaining "numeric" variable is a factor. What does:
class(my_numeric_variable)
say? (where you substitute the name of your "numeric" variable)

Hello, my name is Fábio and I'm a Marine Ecology student in Portugal.
I'm currently using the FD package for my work and yesterday one message
appeared that I wasn't expecting and I really need your help to try to
figure out what's happening.
I'm using the dbFD function and the following message a
