Hi,
I'm a very new user of R and I hope not to be too basic (I tried to
find the answer to my questions by other ways but I was not able to).
I have 12 response variables (species growth rates) and two
environmental factors that I want to test to find out a possible

If you possibly can, you should get some local statistical advice.
There are a number of pitfalls involved in what you're doing.
Frank Harrell's book is a good reference, but may be too advanced
if you are a beginner. You are right on the edge of having too little
data for what you want to do
