[R] making scatter plot points fill semi-transparent

[Kika Tarsi]

Hey hey,

I know that this thread is old, but no one seemed to provide the answer.
Yes, there is absolutely a way to bring in transparency while still using normal colornames.

Just use this code when specifying your color: 
col=adjustcolor("colorname", alpha=0.5)

Alpha values can range from 0 to 1
