R: Extract or Replace the Plot Arguments of a Layered Object

layerplotargs {spatstat.geom} | R Documentation

## Extract or Replace the Plot Arguments of a Layered Object

### Description

Extracts or replaces the plot arguments of a layered object.

### Usage

    layerplotargs(L)

    layerplotargs(L) <- value

### Arguments

`L` | An object of class `"layered"` created by the function `layered`.
`value` | Replacement value. A list, with the same length as `L`, whose elements are lists of plot arguments.

### Details

These commands extract or replace the `plotargs` in a layered object. See `layered`.

The replacement `value` should normally have the same length as the current value. However, it can also be a list with one element which is a list of parameters. This will be replicated to the required length.

For the assignment function `layerplotargs<-`, the argument `L` can be any spatial object; it will be converted to a `layered` object with a single layer.

### Value

`layerplotargs` returns a list of lists of plot arguments.

`"layerplotargs<-"` returns the updated object of class `"layered"`.

### Examples

       W <- square(2)
       L <- layered(W=W, X=cells)
       ## The following are equivalent
       layerplotargs(L) <- list(list(), list(pch=16))
       layerplotargs(L)[[2]] <- list(pch=16)
       layerplotargs(L)$X <- list(pch=16)

       ## The following are equivalent
       layerplotargs(L) <- list(list(cex=2), list(cex=2))
       layerplotargs(L) <- list(list(cex=2))
