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

Dear
R users,
We
are working on a project called,"Environmental Impact Assessment".
We are stationed
at alpine regions of Ireland to see the impact of rainfall on
localities. We have
divided our study area into 92 stations. We have also collected 1 year data
>from each station. Afterwards we placed data into a matrix in such a way that
we got 366*92 matrix. 366 stands for number of days.
What
we want is a lognormal probability plot, of each station(which is individual
column of matrix) with normal reduced variant on x-axis. In this
way, we should
be getting, at the end, 92 curves, one for each station, on same coordinate
axis.
Kindly
help us on that. We are all very new to R.

Dear R users,
You can literally safe my
life my telling me the solution of my problem. I have created matrix
of a data
frame with 3 columns, with each column representing data of
different year.

...snipped useless srting of numbers mangled by mailer processing of
HTML.

I now want to plot "Lognormal
probability plot" of each column data against its respective "normal
reduced
variante(z)".
"Normal reduced variate"? What is that? Is it a set of numbers that
have been centered and scaled, also known as a z-transform? If so, I
do not think it should affect the results of a probability plot since
it is just a linear transformation and the theoretical quantiles will
be unaffected.
You might look at qqplot()
How to do that?
If you don't know the
answer, consider me dead.
What greater lifesaving project are you trying to accomplish, ....
other than getting homework done?
