R help - Aug 2012 - adding tick labels to tileplot()

Hi all - 

 

I am far from fluent in R and need some help polishing up a figure I am
trying to create. I wish to make a "tileplot" (from package
extraLattice)
where the x axis is time (months; may - sept) and the y axis is space
(fishery management zones). Here is my code so far:

 

tileplot(effort~month_num*-area_num,mae,col.regions=topo.colors(100),

               border = "black",

               pch = ifelse(is.na(mae$effort), 4, 21),

               panel = function(...){

               panel.fill("black")

               panel.voronoi(...)

               })

 

This produces axis that looks something like (except with colored tiles):

 

-1

-2

-3

-4

-5

-6

-7

-8  

     5  6  7  8  9

 

But I'm hoping to have tick labels that look like:

 

T

N

C

B

KC

FB

SF
MO

       May  June  July  August September

 

Thanks in advance for any insight.

I'm guessing that you meant to write: latticeExtra

The help page for xyplot has information about the scales argument  
which is what you should constructing when you want to modify the plot  
axis annotation in lattice functions.

perhaps something like scales=list(
                                 x=list(at=1:5, labels=c('May' ,  
'June','July','August','September') ),
                                 y=list(at=(-8):-1,  
labels=c('T','N','C','B','KC','FB','SF','MO'))
                                   )
