[R] (Newbie) using par() to regulate viewing area in graphs
Hello: I should first apologize for the very basic question, but I ought to start from somewhere [embarrassed grin]. I am using R-1.0.0 in a Windows 98 machine to plot some graphs. I tried to apply a "zoom in" in some portions of the graph using say 'par(yaxp=c(0.35,0.40,5))' but nothing happens, no error msg, no update in the active graphics device. What should be the procedure to "zoom in" in a graph? BTW, besides the manuals that come with R ("An introduction to R", "R Reference Manual", "R Extension Writer's Manual", and the "Data Analysis and Graphics Using R - An Introduction", by Maindonald), is there any source of information I should refer to before posting my (newbie) questions to this list? Thanks for all the assistance, Eiji -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- 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 !)

You'll have to change the settings and redo the graph. If it's a complicated graph, you should pack the commands into a small function. It's more convenient. If you upgrade to R 1.11 (which I'd do anyway), you can save a plot to a variable and recall it later (although not with different settings). Still, you can then easily compare several versions.
