Value

• A ``trellis'' object is a list with the following components:
• formula
  formula that was used in the call. Not used
• fname
  function that produced the object. Not used
• aspect.fill
  logical specifying whether aspect==``fill''
• aspect.ratio
  numeric, aspect ratio to be used IF aspect.fill is FALSE
• as.table
  logical, whether rows are drawn top to bottom
• cond
  The conditioning variables. Not used
• key
  list defining the key to be drawn
• layout
  layout of the trellis. Must be of length 3, but first element can be 0, in which case the second element is taken to be the desired number of panels per page and a `nice' layout is calculated based on aspect ratio, screen dimensions etc.
• page
  the page function
• panel
  the panel function
• 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. If skip=T for a particular panel, then the corresponding element is FALSE instead of a list.
• panel.args.common
  a list containing the arguments common to all the panel functions in name=value form
• par.strip.text
  list containing graphical parameters cex, col, font for the strip labels
• skip
  logical vector, not used
• strip
  the function to draw the strip labels
• main
  NULL, or list with components label, cex, col, font
• sub
  same as main
• xlab
  same as sub
• ylab
  same as xlab
• x.draw
  logical specifying whether x-axis is to be drawn
• y.draw
  logical specifying whether y-axis is to be drawn
• 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, same as x.scales
• x.between
  numeric vector of interpanel x-space
• y.between
  numeric vector of interpanel y-space
• x.relation.same
  logical, whether x-relation = "same"
• y.relation.same
  logical, whether y-relation = "same"
• x.alternating
  numeric vector, with components 0, 1 or 2, defining on which side x-axis labels are to be drawn
• y.alternating
  numeric vector, with components 0, 1 or 2, defining on which side y-axis labels are to be drawn
• fontsize.normal
  default fontsize
• fontsize.small
  fontsize for the axis labels, can be further modified by the cex component of scales.
