By range on the y-axis, do you mean distance? It would have to be if time is
on your x? Or am I misreading this?
You could just plot() with the data for your first individual, and then add
additional individuals after that using lines(), specifying a different

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.
