Dear R users, do you know an easy way (other than star plot) of making several points laying one over another visible? Is it any simple way of increasing such "multipoint" symbols - or shifting their positions randomly to make several points in one place visible?
You can make them with transparent colors ... or you can make them small and jitter the x and y values,... or you can use hexbin plots... or you can use 2d density plots or.... probably other ways. We don't really have a very good problem description yet, so it is difficult to be very helpful. Why not read the Posting Guide and see if cam be more complete along its guidelines.

Hi Szymek, The cluster.overplot and count.overplot functions (plotrix) provide two ways to do this. If you have lots and lots of points, count.overplot will be more useful. Jim
Thank you everyone for useful tips! It seems it's not that difficult! Cheers sz.
