R help - May 2010 - Graphing Titration Curves, how to graph in R

I am working on a script with R to calculate pKa values. I want to be able
then to graph pKa values to Energy, basically two variables which will give
me titration curves. It is basically a graph with two variables and help
with just graphing it will be just fine. But if anyone is familiar with
titration curves and R, that would be really great if they can help me out!
Are there any resources out there to help with doing this, how to create a
graph with pKa values. Thanks!

Hi Amitoj,
Most of the titration curves I found could be produced with some 
variation of:

plot(volume,pH,type="l",...)

there is a specialized (free) plotting package here:

Hi Amitoj,
Also look at the AquaEnv and titan packages.
