Halo i'm studying chemistry, today we made an experiment and i have to draw a titration kurve for my mess data. we can do it on a mm paper, or we can also use a programe. people from chemistry recomend "R" last year i studied civil eng. and we used Matlab, as I see, R ist very similar to it, but its got other comands. But i think R would be a good help for some exercises. so my main question is: i have some measurement data from my titration, and I want aproximate a kurve to this data. is it possible to do it with R? a titration kurve looks like this: http://www.nabble.com/file/p25685986/acetic-acid-titration-curve.png hope you can help me, and yes when its possible, if you know something like a tutorial then i would be glad if you could post it. with regards -- View this message in context: http://www.nabble.com/aproximate-a-titration-kurve-to-the-measure-data.-tp25685986p25685986.html Sent from the R help mailing list archive at Nabble.com.
Hi, This should be possible, even with automatic EP detection. Can you give use some example titration data, or the used matlab code? If you want some introduction papers to R, take a look at the documents at CRAN (CRAN > other) Bart awayguy wrote:> > Halo > > i'm studying chemistry, today we made an experiment and i have to draw a > titration kurve for my mess data. we can do it on a mm paper, or we can > also use a programe. people from chemistry recomend "R" > last year i studied civil eng. and we used Matlab, as I see, R ist very > similar to it, but its got other comands. > But i think R would be a good help for some exercises. > > so my main question is: i have some measurement data from my titration, > and I want aproximate a kurve to this data. is it possible to do it with > R? > > a titration kurve looks like this: > > http://www.nabble.com/file/p25685986/acetic-acid-titration-curve.png > > hope you can help me, and yes when its possible, if you know something > like a tutorial then i would be glad if you could post it. > > with regards >-- View this message in context: http://www.nabble.com/aproximate-a-titration-kurve-to-the-measure-data.-tp25685986p25695773.html Sent from the R help mailing list archive at Nabble.com.
