[R] Highlighting a few bars in a barplot

[RINNER Heinrich]

Hello Daniel,

something like that might work:

x <- runif(6)
marker1 <- rep(c("red", "blue"), 3)
marker2 <- c(rep(0,5), 10)
barplot(x, col = marker1)
barplot(x, density = marker2, add=T)

But I'd be interested if you learn about other solutions...

-Heinrich.
