I'm trying to plot some data from the past 12 months and the lattice package is
not labeling the time axis correctly.  It shows only two labels instead of the
expected 12.  The base graphics get it right.  

I think the problem is the commented-out line in formattedTicksAndLabels.Date in
lattice's axis.R:
    ## z <- c(range, x[is.finite(x)])

The following example demonstrates the problem:

require(lattice)  #lattice_0.14-16

x <- rnorm(12)
t <- seq( as.Date("2006-04-01"),by="month", length=12)

plot(x~t)      # Has labels "May", "Jul", "Sep", "Nov", Jan", "Mar"
xyplot(x~t)    # Has labels "Jan", "Mar"
