[R] How to generate this type of scatter plots in R

[array chip]

Hello everyone,

I saw this scatterplots from a paper and thought it looked very nice:

It was similar to stripchart() with 'jitter' method, but it has a special pattern of aligning points which made it look nicer than standard stripchart().

Does anyone know if there is a package in R that can do this kind of plots?

Thanks,

John
