R: Plot a List of Images

plot.imlist {spatstat} | R Documentation

## Plot a List of Images

### Description

Plots an array of pixel images.

### Usage

      ## S3 method for class 'imlist'
    plot(x, ..., plotcommand="image",
                              equal.ribbon=FALSE, ribmar=NULL)

      ## S3 method for class 'imlist'
    image(x, ..., equal.ribbon=FALSE, ribmar=NULL)

      ## S3 method for class 'listof'
    image(x, ..., equal.ribbon=FALSE, ribmar=NULL)

### Arguments

`x` | An object of the class `"imlist"` representing a list of pixel images. Alternatively `x` may belong to the outdated class `"listof"`.
`...` | Arguments passed to `plot.solist` to control the spatial arrangement of panels, and arguments passed to `plot.im` to control the display of each panel.
`equal.ribbon` | Logical. If `TRUE`, the colour maps of all the images will be the same. If `FALSE`, the colour map of each image is adjusted to the range of values of that image.
`ribmar` | Numeric vector of length 4 specifying the margins around the colour ribbon, if `equal.ribbon=TRUE`. Entries in the vector give the margin at the bottom, left, top, and right respectively, as a multiple of the height of a line of text.
`plotcommand` | Character string giving the name of a function to be used to display each image. Recognised by `plot.imlist` only.

### Details

These are methods for the generic plot commands `plot` and `image` for the class `"imlist"`. They are currently identical.

An object of class `"imlist"` represents a list of pixel images. (The outdated class `"listof"` is also handled.)

Each entry in the list `x` will be displayed as a pixel image, in an array of panels laid out on the same graphics display, using `plot.solist`. Individual panels are plotted by `plot.im`.

If `equal.ribbon=FALSE` (the default), the images are rendered using different colour maps, which are displayed as colour ribbons beside each image. If `equal.ribbon=TRUE`, the images are rendered using the same colour map, and a single colour ribbon will be displayed at the right side of the array. The colour maps and the placement of the colour ribbons are controlled by arguments `...` passed to `plot.im`.

### Value

Null.
