R: get the RNG and seed from an object

getRNG {setRNG} | R Documentation

## get the RNG and seed from an object

### Description

Get the random number generator and seed used to generate an object.

### Usage

        getRNG(e=NULL)
        ## Default S3 method:
    getRNG(e=NULL)

### Arguments

`e` | an object generated by simulation (which stored the RNG information).

### Details

Extract the RNG information used to generate the object. If `e` is `NULL` then `getRNG` returns the RNG setting, as returned by `setRNG()`. Otherwise, the default method assumes the object is a list and the RNG information is in the element `rng` or `noise\$rng`.

### Value

The random seed and other random number generation information used to generate the object.

### See Also

`setRNG`, `.Random.seed`

      sim <- simulate(model)
      getRNG(sim)
      }
