Fellow Scientists, Please help me. I have environmental data (73 observations and 8 variables) and species data (73 observations and 24 variables). After running code, get the following error: Error in cca.default(d$X, d$Y, d$Z) :?? all row sums must be >0 in the community data matrix However the code run just fine when use another species data with more variables (73 observations and 169 variables) Thank You In advance.S.
