Adding information on a graph using R

Frage
I would like to add some information on my graph which was plotted from this data set:
EDITTED:
#data set:
day <- c(0:28)
ndied <- c(342,335,240,122,74,64,49,60,51,44,35,48,41,34,38,27,29,23,20,15,20,16,17,17,14,10,4,1,2)
pdied <- c(19.1,18.7,13.4,6.8,4.1,3.6,2.7,3.3,2.8,2.5,2.0,2.7,2.3,1.9,2.1,1.5,1.6,1.3,1.1,0.8,1.1,0.9,0.9,0.9,0.8,0.6,0.2,0.1,0.1)
pmort <- data.frame(day,ndied,pdied)
> pmort
day ndied pdied
1 0 342 19.1
2 1 335 18.7
3 2 240 13.4
4 3 122 6.8
5 4 74 4.1
6 5 64 3.6
7 6 49 2.7
8 7 60 3.3
9 8 51 2.8
10 9 44 2.5
11 10 35 2.0
12 11 48 2.7
13 12 41 2.3
14 13 34 1.9
15 14 38 2.1
16 15 27 1.5
17 16 29 1.6
18 17 23 1.3
19 18 20 1.1
20 19 15 0.8
21 20 20 1.1
22 21 16 0.9
23 22 17 0.9
24 23 17 0.9
25 24 14 0.8
26 25 10 0.6
27 26 4 0.2
28 27 1 0.1
29 28 2 0.1
I have put together this script and still trying to improve on it so that the rest of the information can be added:
> barplot(pmort$pdied,xlab="Age(days)",ylab="Percent",xlim=c(0,28),ylim=c(0,20),legend="Mortality")
I am trying to insert the numbers 0 to 28 (age in days) on the x-axis but could not and I know that it could be a simple script. Secondly, I would like to add the number died or ndied (342 to 2) below each day(0 to 28) along the x-axis.
Example:
0 1 2 3 4 5 and so on...
(N=342) (N=335) (N=240) (N=122) (N=74) (N=64)
Graph:
Any help would be appreciated.

I gave you two ways to plot the info: one above the bars and one below. You can tweak it to meet your needs.
barX <- barplot(pmort$pdied,xlab="Age(days)",
ylab="Percent", names=pmort$day,
xlim=c(0,28),ylim=c(0,20),legend="Mortality")
text(cex=.5, x=barX, y=pmort$pdied+par("cxy")[2]/2, pmort$ndied, xpd=TRUE)
barX <- barplot(pmort$pdied,xlab="Age(days)",
ylab="Percent", names=pmort$day,
xlim=c(0,28),ylim=c(0,20),legend="Mortality")
text(cex=.5, x=barX, y=-.5, pmort$ndied, xpd=TRUE)
