Hello, my name is F?bio 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 appeared: FRic: Only categorical and/or ordinal trait(s) present in 'x'. FRic was measured as the number of unique trait combinations, NOT as the convex hull volume. FDiv: Cannot be computed when only categorical and/or ordinal trait(s) present in 'x'. My data: x is a matrix with species vs functional traits a is a matrix with species vs sampling (in abundances) Previously I used the dbFD function and was working just fine. Yesterday I removed 2 traits and this message appeared. My traits now are 3 categorical traits and 1 numeric. The 2 trais that I removed were numeric traits as well. I really need to remove those trait, but I still need the FDiv to be calculated. Can you explain to me why is this error occurring? I need to know how the dbFD is measuring the indexes so I can understanding the error and if I can or can't continue to use this package (if it applies or not to my goals) Kind regards F?bio Monteiro

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) Jim On Fri, Mar 4, 2016 at 2:25 AM, Fabio Monteiro

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 2016-03-03 23:42 GMT+00:00 Jim Lemon <drjimlemon at gmail.com>:

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) Jim On Fri, Mar 4, 2016 at 11:30 AM, Fabio Monteiro
