Are centre coordinates or upper left corners used of x, y for SpatialPixels?
...;x"], spatial["y"]), proj4string = proj) SP <- SpatialPixels(S, proj4string = proj, tolerance = 5e-07) GRID <- SpatialPixelsDataFrame(points = SP , tolerance = 5e-07, data = spatial[columnname]) proj4string(GRID) <- proj gridded(GRID) nr <- 30 zaxis <- c(0.7, 1) plot(as(GRID, "Spatial"), axes=T) title(main = paste(" Day ",dy[i,1], " Year ",dy[i,2], sep="")) image(GRID, zlim=zaxis, col=rainbow(nr,start=0, end=2/6),add=T) Thanks for your help, Regards, Jan Ps. Is this good approach to plot...

scatterplot3d with categorical data
Dear users, I'm trying to produce a 3d bar plot but the x and y dimensions have categorical data -- so I only want 3 points on each axis. So I try: require(scatterplot3d) mymat<-data.frame( x=c(1,1,1,2,2,2,3,3,3), y=c(1,2,3,1,2,3,1,2,3), z=c(1,2,3,4,5,6,7,8,9)) scatterplot3d(mymat, type="h", lwd=5, pch=" ", xlab="xlabel",
