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. -- View this message in context: h...

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 -- View t...

Hi, I have a dataset that I am trying to analyze and plot as an ordered logistic regression (y = ordinal categories 1-3, x = continuous variable with values 3-9). First is a problem with cdplot: Produces a beautiful plot, with the "right" trend, but my independent factor values are transformed. The factor has values from 3-9, but the plot produces an x-axis with values from 20-140. When I force the xlim to be 3-9, it produces a plot without the trend, which can't be correc...

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 th...

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) :

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

...unlike R). o Experimental versions of cbind() and rbind() in methods package, based on new generic function cbind2(x,y) and rbind2(). This will allow the equivalent of S4 methods for cbind() and rbind() --- currently only after an explicit activation call, see ?cbind2. o New functions cdplot() and spineplot() for conditional density plots and spine plots or spinograms. Spine plots are now used instead of bar plots for x-y scatterplots where y is a factor. o checkDocFiles() in package 'tools' now checks for bad \usage lines (syntactically invalid R code)....
