cdplot error
Fairly new at this.
Trying to create a conditional density plot.
>cdplot(status~harvd.l,data=phy)
Error in cdplot.formula(status~harvd.l,data=phy):
dependent variable should be a factor
What does this error mean? Status is a binary response of infestation (0/1)
and harvd.l is the log of timber harvest density per catchment.
Thanks.

cdplot????
I am having difficulties interpreting a cdplot, I have a binary variable y
that I want to cdplot against a continuous variable x,below is the R command
cdplot(y~x, data=mydata)
you get a plot with a dark shaded area and a light shaded area. what do
these areas mean? and how to interpret the plot?
you help is greatly appreciated

cdplot() with 'POSIXct' x
Hi,
Given that cdplot() is used to produce the conditional density of a
categorical y along a numerical x, it seems natural that it could be
used with a date or time x (such as 'POSIXct'). Is this desirable? If
so, I've created a patch that would allow this, by coercing the POSIXct
x variable to produce the density, but use the original POSIXct x to
draw the x axis.

Plot binomial regression line
Dear all,
I am quite new with R and I have a problem with plotting a binomial
regression line in a plot.
This is what I type in:
> model<-glm(Para~Size,binomial)
> par(mfrow=c(1,1))
> xv<-seq(3.2,4.5,0.01)
> yv<-predict(model,list(area=xv),type="response")
> plot(Size,Para)
> lines(xv,yv)
The error message that I get is:
> Error in xy.coords(x, y) :

comparative density estimates
I have two series of events over time and I want to construct a graph of the
relative frequency/density of these events that allows their
distributions to
be sensibly compared. The events are the milestones items in my project on
milestones in the history of data visualization [1], and I want to
compare trends
in Europe vs. North America.
I decided to use a graph of two overlaid density
