[R] variable in annotation, ggplot2

[Rui Barradas]

Hello,

If you form the label with paste before the plot, it can display both 
values. Something like


lab <- paste("V = ", paste(V, collapse = ","))

ggplot(df,aes(x=x,y=y)) + geom_line() +
   annotate("text", x = 3, y = 20, label = lab)


Hope this helps,

Rui Barradas
