It sounds like one of your columns is all zeros. Look at the input data to make
sure all observations have positive values.

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. Khanyile
