I have 2 series of variables, I want to plot the probability density function of these 2 variabels (i.e. two curves in one graph), I just want to compare these two variable distribution. what should I do? can I use ggplot2 package? -- View this message in context:

x=rnorm(100,1,0.8) # A series. y=rnorm(100,0,0.5) # Another series with different mean and variance. plot(density(x),ylim=c(0,1)) lines(density(y),col=red) Remember that density() is a nonparametric estimator. You should properly choose the bandwith. -- View this message in context:

i want to plot probability density function,predictvalue has missing value and observevalue has not missing value, I tried .. attach(test) #test is the name of the data file names(test) plot(density(predictvalue,na.rm=TRUE)) lines(density(observevalue)) is it correct? -- View this message in

Assuming you mean you want them on the same device: layout(1:2) plot(density(a)) lines(density(d),col=2) plot(density(b)) lines(density(e),col=2) Getting your data into R is more of a challenge, but if you want my unsolicited advice, you can do far worse than saving as CSV and using read.csv()
