R: Random sign

RMsign {RandomFields} | R Documentation

## Random sign

### Description

`RMsign` defines a random sign. It can be used as part of the model definition of a Poisson field.

### Usage

    RMsign(phi, p)

### Arguments

`phi` | shape function of class `RMmodel`.
`p` | probability of keeping the sign

### Details

`RMsign` changes the sign of the shape function `phi` with probability `1-p` and keeps it otherwise.

### Value

`RMsign` returns an object of class `RMmodel`

### Note

Random univariate or multivariate objects are usually start with `RR` not with `RM`. This is an exception here, as it operates on shape functions.

### Examples

    RFoptions(seed=0) ## *ANY* simulation will have the random seed 0; set
    ##                   RFoptions(seed=NA) to make them all random again

    model <- RPpoisson(RMsign(RMtent(), p=0.8))
    x <- seq(0, 10, 0.02)
    plot(RFsimulate(model, x=x))
