[R] legend problems in lattice

2006-09-07 Thread Ernst O Ahlberg Helgee
Hi!
Im sorry to bother you but I cant fix this.
I use the lattice function levelplot and I want the colorkey at the 
bottom, how do I get it there? I have tried changing colorkey.space and 
changing in legend but I cant get it right, plz help

btw I'd like to speceify strings to appear at the tick marks and also 
there I fail any thoughts?

cheers
Ernst

Hi, Ernst,

Please read ?levelplot. Under the argument for colorkey you will see:

colorkey: logical specifying whether a color key is to be drawn
   alongside the plot, or a list describing the color key. The
   list may contain the following components:


   'space': location of the colorkey, can be one of 'left',
'right', 'top' and 'bottom'.  Defaults to
'right'.


So the answer to your first question is:

levelplot(..., colorkey = list(space = bottom))

For your second question, use the scale argument. See ?xyplot for 
details. For example,

levelplot(..., scale = list(x = list(at = 1:4, labels = letters[1:4])))

HTH,
