Hi Juta, some time ago I came across that approach proposed by Dan Warren on his blog: http://enmtools.blogspot.com/2015/10/handy-little-snippet-of-r-code-for.html Maybe this will be useful for you as well? Santiago this figure looks quite nice. Do you have the R code to generate it? I found the description of that function but I will understand it better if I'll have the example and I didn't used ggplot2 for maps so far. Best regards, Kamil
