| scatter.thinning | R Documentation | 
Remove points from a scatter plot where density is really high
scatter.thinning(x, y, resolution = 100, max.per.cell = 100)
x | 
 x-coordinates vector  | 
y | 
 y-coordinates vector  | 
resolution | 
 number of partitions for the x and y-dimensions.  | 
max.per.cell | 
 maximum number of points per x-y partition.  | 
index into the points that omits points from x-y partitions
so that each has at most max.per.cell points.
