Several options:
# See ?sunflowerplot
sunflowerplot(f)
# See ?xyTable referenced in the above
coords <- xyTable(f)
plot(coords$x, coords$y, cex = coords$number)
or
coords <- xyTable(f)
plot(f, type = "n")
text(coords$x, coords$y, labels = coords$number)
# See ?jitter
plot(jitter(f$x), jitter(f$y))
HTH,
