Problem with dbFD function in FD library
...des 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? Func.div?dbFD ( trait_data, abundance_data, calc.FRic = T, corr...
