Hello I wonder whether someone can tell me what I am doing wrong. Here is the code (from Bayesian Computation with R - Chapter 2.3.R) that I am trying to run #################################### # Section 2.3 Using a Discrete Prior #################################### graphics.off() # Close all graphics rm(list=ls()) # Clear all variables library(LearnBayes) library(lattice) p = seq(0.05, 0.95, by = 0.1) prior = c(1, 5.2, 8, 7.2, 4.6, 2.1, 0.7, 0.1, 0, 0) prior = prior/sum(prior) windows() plot(p, prior, type = "h", ylab="Prior Probability") post = pdisc(p, prior,c(11, 16)) print(round(cbind(p, prior, post),2)) # Lattice Library PRIOR=data.frame("prior",p,prior) POST=data.frame("posterior",p,post) names(PRIOR)=c("Type","P","Probability") names(POST)=c("Type","P","Probability") xydata=rbind(PRIOR,POST) windows() xyplot(Probability~P|Type,data=xydata,layout=c(1,2),type="h",lwd=3,col="blac k") # Last command Although there is no warning or error msg after running the code (source("Chapter.2.3.R"), nothing shows up on the second window. However when I issue the last command after the prompt on the command line a graphics shows up. What could be wrong? Many thanks Ed [[alternative HTML version deleted]]

Yes, you were right. Although I have browsed the FAQ I did not connect the dots ...
