rprocess
simulates the process-model portion of partially-observed Markov process.

an object of class ‘pomp’, or of a class that extends ‘pomp’.
This will typically be the output of |

a numeric vector (length |

additional arguments are ignored. |
When rprocess
is called, the first entry of times
is taken to be the initial time (i.e., that corresponding to xstart
).
Subsequent times are the additional times at which the state of the simulated processes are required.
rprocess
returns a rank-3 array with rownames.
Suppose x
is the array returned.
Then

where nvars
is the number of state variables (=nrow(xstart)
),
nrep
is the number of independent realizations simulated (=ncol(xstart)
), and
ntimes
is the length of the vector times
.
x[,j,k]
is the value of the state process in the j
-th realization at time times[k+offset]
.
The rownames of x
must correspond to those of xstart
.
