Dear R Gurus, I have a problem related to plot. For example, I have two variables, pre and post. pre <- c(1,2,3,4,5) post <- c(2,5,7,2,3) How can I plot a line graph similar to this one? http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1847566&rendertype=figure&id=F1 Would you please provide me a keyword so that I can search. I don't know what is the name of this type of graph.
Hi Chainsaw (both my wife and I like chainsaws), I would use lines - I don't know of any specific function that will do this. pp.mat<-cbind(pre,post) plot(1:2,c(1,7),type="n",xaxt="n") axis(1,at=1:2) apply(pp.mat,1,lines) Jim
