## Compute density of a scatterplot

### Description

A 2d density is computed by kde2D.

### Usage

    densityscatter(x,y,pch=19,cex=1,ncol=30,grid=100,palette="heat", add=F,...)

### Arguments

`x` | x coordinate of data
`y` | y coordinate of data
`pch` | type of point
`cex` | A numerical value giving the amount by which plotting text and symbols should be magnified relative to the default
`grid` | Number of grid points in each direction

    points = 10^4
    x <- rnorm(points/2)
    x = c(x,x+2.5)
    y <- x + rnorm(points,sd=0.8)
    x = sign(x)*abs(x)^1.3
    densityscatter(x,y)
