The .arrangement class

Source: R/plotting-classes.R

This class contains the plotting arrangement information.

Details

These gp* parameters will specify plot parameters that are available with gpar(). gp will adjust plot parameters, gpText will adjust title and legend text, gpAxis will adjust the axes. size adjusts point size in a SpatialPoints object. These will persist with the original Plot call for each individual object. Multiple entries can be used, but they must be named list elements and they must match the ... items to plot. This is true for a RasterStack also, i.e., the list of named elements must be the same length as the number of layers being plotted. The naming convention used is: RasterStackName$layerName, i.e, landscape$DEM.

Slots

rows

numeric. Number of rows in the arrangement.

columns

numeric. Number of columns in the arrangement.

actual.ratio

numeric. Ratio of columns to rows

ds.dimensionRatio

numeric. Ratio of the device size to the ratio of the extents.

ds

numeric of length 2. The dimensions of the plotting window in inches.

objects

list of length number of spatial objects. Each list has a character vector of the layer names in each of those.

isRaster

logical vector, indicating whether each object is a Raster* object.

names

character vector, indicating the names of the layers in the plot.

extents

list of class Extent objects. These are needed to calculate the ds.dimensionRatio, which is used to scale the Spatial* objects correctly.

isSpatialObjects

logical indicating whether the object(s) are spatialObjects or not.

layout

list of length 2, with width and height measurements for layout.

gp

a gpar object or list of named gpar objects. These names must match the names of the ... objects. Default is NULL. See details.

gpText

a gpar object or a list of named gpar objects. These names must match the names of the ... objects. Default is NULL. See details.

gpAxis

a gpar object or a list of named gpar objects. These names must match the names of the ... objects. Default is NULL. See details.

size

a numeric or a named list of numerics, used for SpatialPoints plots. Default is 5. See details.
