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

http://lmdvr.r-forge.r-project.org/figures/figures.html

for ideas

Regards

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
