Hi R users, I have a maybe strange problem.
Normaly I do image.plot() with x,y coordinates and add=T and if I have some NA values in my data matrix z, the color will be transparent of these pixels. But now I have a disorted coordinate system and x,y are a matrix. It works also fine, but now NA values are white colored and not transparent anymore. It is problematic if I have a secondary information underlying. Is there any solution for this stuff? Thanks! best regards -- View this message in context: http://r.789695.n4.nabble.com/image-plot-transparent-tp4635976.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
