R help - Jun 2008 - Problem with densityplot from the lattice package

Dear list,

I just experienced some strange behavior of the densityplots provided by the
lattice package. Depending on the values for "from" and "to"
that are passed on to the function for kernel density estimates, the densityplot
excludes the jittered stripplot that is routinely included in lattice
densityplot.


Example:

library(lattice)
test<-runif(100)
densityplot(test) #the standard density plot without problems
densityplot(test, from=0, to=1) #stripplot is excluded 
densityplot(test, from=-1, to=2) #stripplot is again included

Any hints how I could get the stripplot back in the second example?

Tanks in advance
Malte

Look at the y axis ... so try something like

densityplot(test, from=0, to=1, ylim=c(-0.1, 1.5))

The jittered plot is plotted centred on y=0.
