Hello! I have a contour and I need *to rotate* it 180 degrees counterclockwise and 180 degrees around the x-axis. This is a code. I get all the values from the ncdf file: A = get.var.ncdf(nc, "air", start=c(1,1,1,1), count=c(144,73,1,1)) contour(A) Thank you! -- View this message in context: http://r.789695.n4.nabble.com/How-to-rotate-a-contour-tp3750710p3750710.html Sent from the R help mailing list archive at Nabble.com.
