Hello everyone. I have been dealing with this for a while. I have built a spatial prediction model for densities of mosquitoes on a field, based om empirical data. I need to plot the field area with the predicted densities in a heatmap, contour or likewise, and compare it visually with i.e. a loess prediction (which works well). But no matter what I do, I cannot come across the problem that the x and y values should be in ascending order. Why is this necessary? I have tried using the unique() function as mentioned earlier, but it only removes some data points. Please help me, I will appreciate any advice.
