[R] Changing y-axis in ggplot to show proportions instead of density

[Camilo Mora]

Hi Everyone,

I have a frequency data, which I am displaying with an area-curve-like  
plot in ggplot2 using:

ggplot(dfs, aes(x=values)) + geom_density(aes(group=ind))

The Y-axis that is returned is density, which is not really intuitive  
for my purposes and I would like to change it for proportions (i.e.  
the count of values at each bin divided by the total number of values).

I have found that I can change the y-axis to display counts or scaled  
proportions but not just the proportions.

something like +geom_density(aes(y = count/sum(count)))

This code does not work but I wonder if something like this possible?

Thanks,

Camilo
