phyl.cca(tree, X, Y, lambda=1.0, fixed=TRUE)
tree |
a phylogenetic tree in |
X |
a data matrix with traits in columns. |
Y |
data matrix with traits in columns, to be correlated with |
lambda |
optionally, a (fixed) value for |
fixed |
optionally, a logical value indicating whether or not to estimate |
(Optional) joint optimization of \lambda
is performed using optimize
on the interval (0,1).
