R help - Aug 2010 - Help with Lattice--panel.axis() and a conditioning variable

Hello,

I use the following code to generate this plot: 
http://imgur.com/GsWvY.jpg. How do I remove the labels to the left of 
the middle axis? Or is there a simpler solution that gets me the same 
plot. I basically just want to highlight 25.67 on the leftmost axis, and 
have all other labels black.

axis.ob <- function(side, ...){
    if(side == "left"){
        panel.axis(side = "left", outside = TRUE, at = ybid.at, labels
formatC(price[ybid.at], format = "f", digits = 2),
                   text.col = c("black", "red"), ticks =
FALSE)

    }else if (side == "right"){
        panel.axis(side = "right", outside = TRUE, at = yask.at,
labels                    formatC(price[yask.at], format = "f", digits
= 2),
                   text.col = c("black"), ticks = FALSE)

    }else axis.default(side = side, ...)
}


barchart(price ~ size | type, data = x,

         ylab = "Price", xlab = "Size (Shares)",
         groups = interaction(x$status, x$time),
         main = paste("Order Book", time, sep = " -- "),
         stack = TRUE, sub = sub,
         col = c("gray", "blue", "green",
"red", "black"),
         border = "transparent",
         scale = list(x = list(relation = "free", at = x.at,
                      limits = x.limits, axs = "i", rot = 45),
         y = list(alternating = 3)),
         axis = axis.ob
         )

Thanks,

Andrew
