Hi
Try something like (as you have not given a reproducible example)
library(lattice)
xyplot(y1 + y2+ y3 ... ~ x, data = your data.frame, type = "b",
allow.multiple = TRUE)
Read ?xyplot CAREFULLY as there are many possibilities
you may want to have a look at
library(lattice)
?useOuterStrips
and other functions in the package
See

for ideas

Subject: [R] Line Graph greater than 2 variables on plot
Hi all,
I was wondering if anyone knew how to construct a multiple line graph on R,
where there are 2 (or more) sets of data points plotted against some x axis
of
data, and you can draw a line on the graph connecting each set of data
points.
for example:
time..years. incidence rural urban
1 2004 295.4 19.01 9.50
2 2005 824.1 19.95 9.98
3 2006 1078.0 20.70 10.35
4 2007 1258.0 21.26 10.63
5 2008 1800.0 21.83 10.91
6 2009 1890.0 18.93 9.47
7 2010 1999.0 19.41 9.71
8 2011 2261.0 19.89 9.95
9 2012 2321.0 20.28 10.14
Idea:
a) I am planning plot a graph of data illustrated above where on Y-axis we
can have data in sets INCIDENCE, RURAL and URBAN and on X-axis the points in
set TIME..YEARS.
b) Would like to be able to draw three lines ,connecting the points for each
set of INCIDENCE, RURAL and URBAN over TIME..YEARS.
I have tried really hard to find something but wasn't successful, the latest
information I received after doing the command shown underneath was:
> plot(data1$time..years.,data1$incidence,main="Plot illustrating
diarrhoeal
incidence over time", xlab="Time(years)",ylab="Diarrhoeal
incidence",ylim=range(data[c("incidence","rural","urban")]),type"l",
col=2)
Error: unexpected string constant in
"plot(data1$time..years.,data1$incidence,main="Plot illustrating
diarrhoeal
incidence over time", xlab="Time(years)",ylab="Diarrhoeal
incidence",ylim=range(data[c("incidence","rural","urban")])"
Many thanks,
W
