[R] smoothScatter plot

[JiangZhengyu]

Hi, I want to make a plot similar to sm1 (attached). The code I tried is: dcols <- densCols(x,y)
smoothScatter(x,y, col = dcols, pch=20,xlab="A",ylab="B")
abline(h=0, col="red")
 But it turned out to be s1 (attached) with big dots. I was wondering if anything wrong with my code. Thanks,Zhengyu
