check this:
x <- rnorm(200)
dd <- density(x)
plot(dd)
ind <- seq(100, 400, len = 6)
arrows(dd$x[ind], 0, dd$x[ind], dd$y[ind] - 0.015, length = 0.2)
I hope it helps.
Best,
Dimitris

Quoting mogra <[EMAIL PROTECTED]>:
I use plot to get the density curve and then I use
abline(v=g$V2, col = 3 ) to get the vertical line for specific point on x
axis.
Goal : I want very small lines at the bottom on the x axis , if possible in
the arrow forms instead of vertical lines on the whole graph.
Thanks a lot.
