Thanks Peter,
I think that might actually work. I Will let you know.

Allan,
Simply defining the dimension might work:
dim(v) <- dim(trial2)
but it is not clear what you are trying to achieve with the rep(...,
1000) part. It won't permute the matrix 1000 times but repeat same
values. You might want to have a look at oecosimu in vegan which
calculates the distributio
Dear R ecologists,
I'm trying to figure out a way to calculate the sum of squared
distances (SSD) between two matrices, where one matrix is held
constant and the other is randomized. So far I have been able to get
the syntax together to obtain my observed SSD, but the problem for me
is obtain SSD
