Dear sir,

I am trying to create a barplot showing propotions, 

 So my data is in the format of a vector containing 0s and 1s (i.e.successful or not) with a corresponding vector with two  catogorical levels.

success        age
1                     old
0                    young
0                     young
1                     old

I want to show a bar plot with a ylim=c(0,1) and an x-axis showing the two ages and the proportion of success only as filled bars.

after making success a factor and plotting against age using: plot(success~age)

the graphic shows age on the x and proportion on the yaxis as i want.  However for each age it shows the total proportion split into both success and failures.  I would however just like to show the prop successes without the failures stajed on top.

data frame is below:
