[R] Variate

Hi Eliza

You  will not want 1 panel with 96 lines - too confusing after about 20
Instead 1 per panel or with groups using useOuterStrips  and 
combineLimits from latticeExtra  package

Try this -- a minimal example with an 12 row 8 col grid done on the fly

setseed(12)
Sites <- 1:92
dat <-
data.frame(y = rep(rnorm(5),92), x = rep(1:5,92), site = rep(Sites,each = 5))

xyplot(y ~ x|site,dat,
        as.table=T,
        strip = F,
        layout = c(8,12),
        scales = list(x = list(alternating = 2),y=list(alternating=1)),
        type = "b",
        panel = function(x,y,...){
                 pnl=panel.number()
                 panel.xyplot(x,y,...)
                 panel.text(4,-1.5,Sites[pnl], cex = 0.6)
               }
)

or with groupings for Site something like (untested)

xyplot(y ~ x|groupings,dat,
        as.table=T,
        strip = F,
        strip.left = T,
        groups = site,
        scales = list(x = list(alternating = 2),y=list(alternating=1)),
        type = "b",
        panel = function(x,y,...){
                 pnl=panel.number()
                 panel.xyplot(x,y,...)
                 panel.text(4,-1.5,Sites[pnl], cex = 0.6)
               }
)
You will need an extra column for groupings

This can also be done with the base plot function but lattice gives 
more flexibility, see  ?xyplot  and particularly par.settings into 
get things right size
