Liam,
The package MASS has the function mvrnorm that simulates from a
multivariate normal distribution. Its help page says:
The matrix decomposition is done via 'eigen'; although a Choleski
decomposition might be faster, the eigen decomposition is stabler.
The package mvtnorm (on
Hi Jeremy,
Perhaps you've already figured this out. There may be a function
available in R to do this, but if not, in principle for BM it should be
fairly easy to do this manually.
First, read your tree in:
tree-read.tree(FILE, etc.) % put filename or paste in tree
then compute the
Hi all~
I was just wondering if there is a package or function in R that can simulate
two continuous traits with a user-specified correlation coefficient using a
known tree topology, branch lengths, and a model of Brownian motion (or even
OU, if possible)?
All the best,
Jeremy Beaulieu
