Hello all, I'm hoping this is a simple problem.
I'm trying to do cca of my data. I have my plant data and environmental data as 2 separate files. I have 3 years of data, stacked vertically, within these files. I want to conduct the cca for each year and am trying to create separate year files using the following: cnts94 <- cnts[1:27,] env94 <- env[1:27,] when I run cca(cnts94, env94) I get the following error message: Error in cca.default(cnts94, env94): All row and column sums must be >0 in the community matrix There are no missing data points in the data set. If I run the whole data set: cca(cnts, env) it works, and I can plot and do all the associated stuff. Why not work if I specify a smaller data set? Am I specifying it wrong?
