Hi everybody,
I have a huge  longitude and latitude data. I have used raster package to
get the since of its global distribution. But I wish to display the
information using a few points on the world map.

The data is of the form:
95.2156 0.8312
-65.3236 -3.3851
-65.2364 -3.2696
-65.2349 -3.2679
164.7025 -17.6404
148.8214 -4.8285
-67.6568 2.6477
-73.4833 -0.2350
40.9587 -16.8655
-61.6474 8.1179
93.3401 -0.2755
119.9011 -17.1733
-69.7640 1.1245
-149.3088 -20.0035
177.8753 -3.4200
-67.5590 3.0133
-21.9331 15.4684
120.2656 -17.6166
165.9368 -17.3888
164.7335 -17.6953
-74.0017 -1.8623
-71.1195 -3.3562
130.1496 -11.5775


I am thinking of a way of handling that data in such a way that they can be
represented by fewer points when plotted on the map. I have tried using
factor method but didn't get any way.

Thank you for any idea
