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

Hi,
I have a dataset with couple of million of points (individuals) and
would like to do some mapping (I have the coordinates of each point)
but given the number of observation I think it may be usuful to plot
dots which represent 100 individuals (of a given group). Does anyone
know a good way to aggregate up spatialpoints? Any suggestions would
be much appreciated!
Best wishes,
Juta
