In the absence of data coords <- expand.grid(lat=1:5,long=1:5) coords$z <- rnorm(25) Coords<- unstack(coords,z~long) image(as.matrix(Coords))

I have some data set which has latitude, longitude and Z values. I would like to plot them on global map. I am thinking to use image image(x, y, z, zlim, xlim, ylim, col = heat.colors(12), ? ? ?add = FALSE, xaxs = "i", yaxs = "i", xlab, ylab, ? ? ?breaks, oldstyle = FALSE, useRaster = FALSE, ...) here I have x = longitude ? ? ? ? ? ? ? ? ? ? ? y= latitude ? ? ? ? ? ? ? ? ? ? ?z = z but z suppose to be matrix but my z values are ?single array , could somebody please tell me how to convert these single array of z to matrix ? -- View this message in context: http://r.789695.n4.nabble.com/Plotting-function-image-tp4387796p4387796.html Sent from the R help mailing list archive at Nabble.com.
