You might find image() useful, to plot the factory map and overlay the sound levels as colors. You could also use persp(), or have a look at rgl.surface in the rgl package on http://cran.r-project.org.
Reid Huntsinger -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Philippe Sent: Thursday, August 25, 2005 9:55 AM To: [email protected] Subject: [R] Help about R Hello, My name is Philippe Favrot, I'm a french occupational doctor (working in Luxembourg), and I'm an "R beginner". I would be happy you could help me about the utilization of "R". Recently, I measured sound levels in a plant. Before the measuring, I divided the plant in 3 virtual rows and 8 virtual columns. I measured the sound level at each intersection of rows and columns and obtained a set of 24 "sound level" values. I wrote the results in a excel's spreadsheet. My question is: I know to do import from excel into "R" (with read.table()), but how can I draw a three dimensional graphic of the plant's sound level ? Can I overlay a map of this factory (as a rectangle with a grid representing each spots where I measured )? I'd understand if you are too busy to reply to my mail. Thanks.
