trellis.object: A Trellis Plot Object

Description

This class of objects is returned by high level lattice display functions, and is usually plotted by default by its `print' method.

Value

• A trellis object, as returned by high level lattice functions like xyplot, is a list with the ``class'' attribute set to ``trellis''. Many of the components of this list are simply the arguments to the high level function that produced the object. Among them are:
  • as.table
• layout
• page
• panel
• prepanel
• main
• sub
• par.settings
• par.strip.text
• strip
• skip
• xlab
• ylab

describe

• index.cond
  list with index for each of the conditioning variables
• perm.cond
  permutation of the order of the conditioning variables
• aspect.fill
• { logical, whether aspect is ``fill'' }
• aspect.ratio
  numeric, aspect ratio to be used if aspect.fill is FALSE
• call
• { call that generated the object. }
• condlevels
• { list with levels of the conditioning variables }
• legend
• { list describing the legend(s) to be drawn }
• panel.args
  a list as long as the number of panels, each element being a list itself, containing the arguments in named form to be passed to the panel function in that panel.
• panel.args.common
  a list containing the arguments common to all the panel functions in name=value form
• x.scales
  list describing x-scale, can consist of several other lists, paralleling panel.args, if x-relation is not ``same''
• y.scales
  list describing y-scale, similar to x.scales
• x.between
  numeric vector of interpanel x-space
• y.between
  numeric vector of interpanel y-space
• x.limits
  numeric vector of length 2 or list, giving x-axis limits
• y.limits
  similar to x.limits
