Hello I'm trying to render in 3D what I usually plot by image(), or image.plot() from the library fields, followed by a map("world",add=TRUE) type of command. More concretely, I have a field of temperature values, for a given geographic area, and I would like to plot a 3D surface whose x and y axes consist of longitude and latitude values and whose height and color-coding correspond to the temperature values but also -- and here is the problem -- superimpose a map of the region. persp() can easily do the color-coded surface but I cannot figure out how (if at all possible) to overlay geographic boundaries, in this specific case a simple map of the land area outlines.
Thank you in advance for any help Claudia -- Claudia Tebaldi Research Scientist, Climate Central http://www.climatecentral.org (303) 775 5365 c (Colorado area code) [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
