I have a question about FD package. I’m trying to calculate functional
diversity indices using insect data. My trait data includes dispersal
ability (0, 0.5, 1), body size (continuous) and five feeding guilds coded
as in percentages (for example; 0,0,0.5,0.5,0) since some of the species
can have two different feeding guilds. However, the package only calculates
when I run “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?
