format axis labels in lattice

How can I put my axis labels in a convenient format in lattice?

require(stats)

xyplot(lat*1000000 ~ long, data = quakes)

gives me y-labels like -3.5e+0.7. I would want lattice to write the whole number.

(maybe it is easy, but I can't find a solution.)

Thank you in advance!

There are a couple of "global options" that might affect how values are printed. In this case scipen is the one you want to move:

old_op <- options(scipen=10)
xyplot(lat*1000000 ~ long, data = quakes)
options(old_op)
# probably better to restore it so the rest of you session is more "normal"

Create your own labels and pass them to the scales argument.

y_at <- pretty(quakes$lat*1e6)
y_labels <- formatC(y_at, digits = 0, format = "f")
xyplot(
  lat*1000000 ~ long, 
  data = quakes, 
  scales = list(
    y = list(
      at = y_at, 
      labels = y_labels
    )
  )
)

For the formatting step, there are lots of alternatives to formatC. Take a look at format, prettyNum and sprintf to get you started.

If you want to do this with dates, then note that scales accepts a format argument for that purpose.
