3you can use `bty="n"` inside `legend` – Ananta Apr 29 '16 at 13:26

1Note also that `legend` accepts the bg argument, so that you can fill in the background with a different color if desired. – lmo Apr 29 '16 at 14:27

Use: bg="transparent" in
legend()
Such as:
legend("right",bg="transparent",col=c(as.numeric(unique(df$group2))),cex=0.5)
