I am trying to do something simple with ggplot. I wish to draw a density
plot split by group, and fill each group with a different colour (and
each with an alpha =0.25). I have tried a number of variations of the
following, but cannot find a way to define the colour of the fill, its
transparency and the line around it individually - something in the
syntax continues to defy me. 

 

ggplot(data.plot, aes(x=x, y=..density..))+

            geom_density(aes(group=group))  

 

I am sure a simple solution is out there. Any help appreciated,


Scott
