Hmm, doesn't work for me. ?factor does not list a 'drop='
argument.

Include individual as a factor in your dataset, and use ggplot2:
library(ggplot2)
ggplot(aes(x=Date, y=Distance, color=Individual), data=data) + geom_line()
ought to do it.

not larger which can achieved by cex=2, but thicker. I tried lwd=2, but it
didn't work. I know lwd works in regular plot() not only for lines, but also
for points. For example
plot(1:10, lwd=2)
Thanks

There is probably a simpler way, but if you want full customization, look at
panel.my.symbols in the TeachingDemos package.

Thank you Greg. I also got it work by using panel.points (lwd=2) instead of
using panel.xyplot()

Now I got point character thicker using panel.points(lwd=2), But I can't make
it
thicker in the legend of the plot. Here is an example:
xyplot(1:10~1:10,groups=rep(1:5,2),col=1:2,pch=0:1,type='p',cex=2,panel=panel.points,lwd=3,
key=list(x=0.7,y=0.2,corner=c(0,0),type='p',

Yes, it does what I want. Thank you Peter! Just wondering what else grid.pars
controls? not just the symbol in legend, right?

You can have a look at ?gpar (after loading package 'grid').
For example, your original request could be handled with

Not sure about packages to suggest but some of this can be done with
base stats...
