[R] Plotting Question

[Steve_Friedman at nps.gov]

Hello,

I would like to produce a series of graphs comparing the probability
distributions for 8 factors against a continuous metric.

The kind of graph I'm hoping to produce would look like the density
comparison graphs (library sm) using the function sm.density.compare.
However, instead of calculating the density distributions for comparisons,
I'd like this comparison to be based on probabilities.

An example of the graph I'm seeking can be seen here:
http://www.statmethods.net/graphs/density.html   (scroll to the bottom and
examine the Comparing Groups via Kernel Density).

A graph (attached) produced using my data:
> attach(SoilVegHydro)

> vegtype.f <- factor(Physiogomy)

 > sm.density.compare(meanAnnualDepthAve, vegtype.f, xlab="Mean Annual
Depth")

  # create color fill patterns
  >colfill <- c(2:(2+length(levels(vegtype.f))))
  > legend(locator(1), levels(vegtype.f), fill=colfill)

(See attached file: MeanAnnualDepth_Density.png)


Thanks
Steve
