...ne blow the other.
I.e.
1979: --...---```--``--..
1980: ...--``../``\...---
...
etc.
Here characters ---...---``` denote the curve.
The middle value is on the vertical axis
and the latitude is on the horizontal axis of each graph.
To do this I use xyplot function from the Lattice package:
xyplot(ac15$"value"~ac15$lon|year,data=ac15,
type="l",
layout=c(1,24),
xlab="Longitude",
as.table=TRUE,
bg="white"
);
But I have some problems using it.
Questions:
1. How to make xyplot to draw the year value in the strip above...

again troubles with lattice
...ample, "a.R", containing
the following
library(lattice);
trellis.device(device="png",
filename="a.png",
color = FALSE,
bg = "white",
width=600,
height=800
);
xyplot(ac15$value~ac15$year|factor(lon),data=ac15,
type="o",
layout=c(1,18),
xlab="year",
);
dev.off();
The structure of ac15 data frame is like following
