How do I sample "cases" within a matrix?
Hi R community,
I am trying to obtain a sample from a matrix but sample(my.matrix) doesn't
do what I need. I have a matrix of 1287 interactions between the species in
columns and the species in rows and I want to obtain a smaller matrix with
say, 800 interactions, that may or may not have the same number of columns
and/or rows (i.e., some interactions may not be retrieved in a smaller
sample).
