R help - Oct 2017 - Add a vertical line and some values on a plot

Dear R-experts,

Here below is my code, 
I would like to add a vertical line on my plot, showing the median and I would
like to place some values on this graph as well, i.e. 4.3 and -8.4. How can I do
?
Many thanks for your reply.



A=c(1,2.3,4,3.5,4.3,2.5,6.3,-0.1,-1.5,3.7,-2.3,-3.5,5.4,3.2, -10.5,-8.4,-9.4) 
d <- density(A)
plot(d)
median(A)

Hello,

After the plot just do

abline(v = median(A))

As for how to plot points, see, well, ?points().

Hope this helps,

Rui Barradas
