rnetwork {deal} | R Documentation |
Given a network with nodes having the simprob
property,
rnetwork
simulates
a data set.
rnetwork(nw, n=24, file="")
nw |
an object of class |
n |
an integer, which gives the number of cases to simulate. |
file |
a string. If non-empty, the data set is stored there. |
The variables are simulated one at a time in an order that ensures
that the parents of the node have already been simulated. For discrete
variables a multinomial distribution is used and for continuous
variables, a Gaussian distribution is used, according to the
simprob
property in each node.
A data frame with one row per case. If a file name is given, a file is created with the data set.
