Hi:

With the same adjustment to the data frame as given previously, this

xyplot(rainfall ~ Time, data = rainfall, type = 'l')
Gabor's solution is nice because it gives you more control over the date
format and the zoo plot method works
Using lattice and the rainfall$Time series as proposed below by Dennis
gives also a nice result:
rainfall$Time - seq(from = as.Date('1993-01-01'),
to = as.Date('2007-12-01'), by = 'month')
xyplot(rainfall~Time,data=rainfall,type=c(g,p,l,smooth))
