Hi everyone,
I have a simple question I can not seem to find a definitive answer to:

I want to compare sample x with sample y.  Do x and y have to have the same
N (i.e., like in a paired t-test)?  In my instance I am comparing samples
from two different areas and the sample sizes are different due to the
nature of the study sites.

I would test this myself using a test datasets but I am using an older
version of R that does not support SpatialPack (the newer version is not
compatible with other packages I am using) so I was hoping for a quick
answer before I delve into a lengthy work around to my version issues.

Many thanks,
TB
