yes, halo thank you. my measure data: v2 <- c(0, 2, 4, 6, 6.2, 6.4, 6.6, 6.8, 7, 7.2, 7.4, 7.6, 7.8, 8, 10, 12, 14) ph2 <- c(12.10, 11.94, 11.68, 11.11, 10.91, 10.74, 10.47, 9.71, 7.1, 4.24, 3.3, 3.08, 2.98, 2.86, 2.33, 2.11, 1.98) with regards bartjoosen wrote: > > Hi, > > This should be poss

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, toda

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
