Thanks a lot to David and William - I think
ggplot( data=ddd, aes(x=pH, y=BC,group=interaction(type,pH),
col=type))+geom_boxplot()
was very helpful!
All best

Hi Troels,
Have you considered using Lattice graphics?
Adapting from examples on the help page:
> ?histogram()
> histogram( ~ BC | pH, data = ddd, type = "density",
xlab = "BC", layout = c(1, 3), aspect = 0.618,
strip = strip.custom(strip.levels=c(TRUE,TRUE)),
panel = function(x, ...)

Dear friends
I'm trying to plot in silico derived values of 3 types of
buffer-capacities over pH values and want densities of the three
types together at each pH with the pH values on the abscissa.
I have generated some data
set.seed(2345)
pHs <-
