spatialpoints: each dot represents 100 individuals?
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.

Hi Juta, Do you need to represent the aggregated data as points necessarily? Otherwise, I have used the stat_hexbin representation from ggplot2 for that very purpose, see for instance: http://santiago.begueria.es/wordpress/wp-content/uploads/2015/06/Figure_01.png Cheers, Stg

Does anyone know a good way to aggregate up spatialpoints? Any suggestions would be much appreciated! Best wishes, Juta
