nlme formula from model specification
...ve been processed by a machine
measuring the same signal at four different channels. I want to model
the noise. I have taken the noise (the signal is from position 1 to
3500, and after that there is only noise).
My data looks like this:

rarefy a matrix of counts
Hi all,
I have a matrix of counts for objects (rows) by samples (columns). I aimed
for about 500 counts in each sample (I have about 80 samples) and would now
like to rarefy these down to 100 counts in each sample using simple random
sampling without replacement. I plan on rarefying several times for each
sample. I could do the tedious looping task of making a list of all objects
(with its
