Hi I am analyzing the surface geometry of plates used in chemical analyzes. For this purpose I am using different plot functions (especially persp), and I have had some problems with these and graphical devices in general. The ref-manual doesn?t seem to help me... Questions: (1) Which parameters is possible to set in the persp-function? I would like to control the size of the plot, but how? I cannot set the fin-parameter... Other parameters that I cannot use are for example las,xaxp,yaxp etc... (2) Can I add lines or curves to a persp plot? (3) Can I set the size of a graphic device? I would like set it so that when I print it the paper is used in a good way! (4) Is there a command that automatically will send a plot to a printer? cheers, Tomas Svensson (R beginner) -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- 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 !)
