[R] Plotting with dates on X axis

[M. Lang & S. Railsback]

Is there a trick to drawing a graph with date-formatted values as one of
the axes?  Here is my code:

  library(date)
  MortDate <-as.date(MortalityDate)
  
  ...

  plot(MortDate,AqPred,type="l", xlim=range(MortDate), ylim=c(0,MaxY))

The plot actually has the formatted date values as the X axis labels,
but they are overwritten by unformatted (integer) Julian dates. 

Then the vector of Julian dates appears underneath the plot as:

 c(14611, 14611, ...

and so on for two lines.

Using the plot parameter xaxt = "t" does not help. 
I'm using R1000 for Windows.

Thanks
