Hello, I'm using R to do survey analysis and plotting. I've gotten good help on this list to sort out specific plotting issues, but I think I could do a lot more on my own if I could find a good reference that explained some of the graphics terms and concepts used by R. I haven't found a general discussion of the graphics environment, with illustrations. Part of my problem is that the help text is all text. There are no figures to illustrate the terms used. For example, I would like to be able to *see* the relationship of these concepts illustrated: figure region device region plot region user coordinates normalized device coordinates margin outer margin Also, there are a number of par settings that apparently work on the same underlying data but using different units. For example, oma, omi, omd; mai and mar. The documentation for "mar" says: "A numerical vector of the form 'c(bottom, left, top, right)' which gives the lines of margin to be specified on the four sides of the plot..." After some experimentation I found that csi * mar = mai, so I guess mar is "lines of text" of size "csi". But all this could be much better illustrated if it were... illustrated. If there is no such introduction with diagrams to show the relation of the different par values, I suppose I could start to create one, but could certainly use help, if only in editing, from someone who actually *knows* how this stuff works. Thanks for whatever guidance you may be able to offer. -Tom -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

Well, you might look at the pages around p.75 in "An introduction to R" which ships with the sources (builds as R-intro.pdf).

There are figures in the PDF/DVI versions of `An Introduction to R' and in Venables & Ripley (any edition of MASS). If you missed `An Introduction to R' you really should look at it. I don't think end users even need to know about `normalized device coordinates'. I am not entirely sure why the HTML version of `An Introduction to R' lacks the figures: probably limitations of makeinfo.
