I'm trying to make a simple contour plot, similar to the example here. However, it fails with "Computation failed in stat_contour(): no proper 'z' matrix specified". library('MASS') library('tidyverse') generate a gaussian density: den = kde2d(x = rnorm(10000), y = rnorm(10000...
It works, but I am not sure if using stat_contour() is the best way to plot the areas. Furthermore, plotting the areas of the islands, it colours also some parts of them, making the shape wired. Do you think to use stat_contour() is the best way to plot the areas, and do you...

Interpret a contour plot Contour plots portray data for three variables in two dimensions. The plot contains a number of contour lines. Each contour line is shown in an X-Y plot and has a constant value on a third variable. Consider the Figure 1 that contains data on the fat, non-sugar...
regular data array, with neatly ordered values in x and y, but nowhere am I generating the actual lines. The contour lines are more complicated, seem to be generated byxyz_to_isolinesin stat_contour (cf.https://github.com/tidyverse/ggplot2/blob/main/R/stat-contour.r, line 97 as of ...
I am trying to make a basic contour plot using 3 point stations using the base map of Mauritius. I am getting this error: Warning messages: 1: `stat_contour()`: Zero contours were generated 2: In min(x) : no non-missing arguments to min; returning Inf 3: In max(x) : n...
