# Re: [R] Simple lattice question

Just a few minor glitches now:

require(lattice)

```data <- data.frame(SP=sort(rep(as.factor(c('A','B','C','D','E')),12)),
x=rpois(60,10),
y=rep(c(rep(0,4),rep(10,4),rep(20,4)),5),
z=rep(1:4,15))
xyplot(x~y|SP,data=data,groups=z,layout=c(2,3),pch=1:4,lty=1:4,col='black',type='b',
key=list(x = .65, y = .75, corner = c(0, 0), points=TRUE,
lines=TRUE, pch=1:4, lty=1:4, type='b',
text=list(lab = as.character(unique(data\$z)))))

```

I have an extra column of symbols on the legend,

and,

would like to add a title to the legend. Such as 'main' for plots.
