From the data frame
X where the possible parents must exist, a
simulation is done for the node
nod. The number of values to
simulate is given by the X row number, so it must be present (even
with zero columns) for ancestor nodes.
The function returns an augmented data frame with a new column (or more according to
nod@format) in last position(s) containing the simulated
/nod/ object to be simulated.
Data frame of the previous simulated nodes in columns. For ancestor nodes can have zero columns or more simply be an integer indicating the desired number of simulations, as it is in the default.

Data frame with the simulated and retained column(s) possibly as an
augmentation of the inputted
