Generate particles from the user-specified distribution. This is part of the low-level interface, used by mif. This help page does not give instruction on how to write a valid particles function: see the documentation for mif instead.

particles(object, ...)
## S4 method for signature 'mif'
particles(object, Np = 1, center = coef(object), sd = 0, ...)

`object`	the `mif` object
`Np`	the number of particles, i.e., number of draws.
`center`	the central value of the distribution of particles
`sd`	the width of the distribution
`...`	additional arguments. At present, these are ignored.

The particles method is used to set up the initial distribution of particles. It is an interface to the user-specifed particles slot in the mif object.

particles returns a list of two matrices. states contains the state-variable portion of the particles; params contains the parameter portion. Each has Np columns.
