seeds |
Matrix of produced seeds (with mother'trait values) as produced by
|
n.traits |
Number of traits |
distribs |
Types of the distributions of traits (see |
distr.parms |
Parameters of distribution (see |
sigma |
Matrix of variance-covariance matrix of traits (see |
ITV.ratio |
Ratio of within/between species variances of traits |
... |
Any additional parameters |
The function uses parameters of Gener.species.pool
. First it
transforms back mother's trait values to multivariate normal distribution.
Then random noise was added to this values. Random noise has multivariate
normal distribution, with zero means and the same correlation structure
as specified in parameter sigma. Note that sigma specifies
covariance matrix, not correlation structure per se. Variances in the random noise
are diagonals (i.e. variance componens) of parameter sigma multiplied by
ITV.ratio. The non-diagonal elements of covariance matrix were specified
to conserve the correlation structure among traits.
