Hi everyone, I know we have a few stats gurus on here, so I hope someone uses and understands R! I'm trying to do some evaluation of an ecological community and environmental factors influencing phytoplankton growth. I need to do a CCA, I have the code and everything but it just won't go and I keep getting an error message I don't understand. The data tables are set up right, I've done other analyses such as Shannon diversity index and Bray Curtis dendrograms etc, but I just can't get this to work.

The code I've used is: abcde.cca<-cca(abcde[,2:66],xyz[,2:29])
The error message is: Error in x * w : non-numeric argument to binary operator

I duno where the error is!

My supervisors have NO clue of R, and I think I've maxed out the only 2 people I know who can help me, so I'm literally in desperation here!

Kindly have a look here, it might helps to solve your headache;
