Hello list I have a theoretical differential equation model (two coupled differential equations) describing the acidification of dairy cultures in milk: dX/dt = f(H, param)*X dH/dt = g(param)*dX/dt pH = -log10(H) I also have actual data of the same. I would like to estimate the parameters of the theoretical model from real data, but don't know how to go about it in R (I'm fairly new to R). Is there an R-package for thi...

Hi all, I'm a PhD student at sydney uni and am trying to run a non linear mixed model program to obtain estimates of parameters describing dairy cow lactation curves. At present, I have been able to get the data to converge using the S plus (S plus 2000) nlme function. However, when I put the same data into R (R 1.9.0), add in the nlme package and run the code, it does not converge by the max 50 iterations. Is this because the nlme functio...

...rk policy on this help list. What do you want to do with your table 3? It seems to me futile. Anyway, some combination of melt, merge, cast and regular expressions could be employed in such task, but it could be rather tricky. But be aware that Suger does not match sugar (I wonder that sugar is dairy product) and you mix uppercase and lowercase letters which could be also problematic, when matching words.

Are there any functions available to calculate sunrise and sunset times for given latitude,longitude and dates? If not, I'll appreciatte any pointers to C code I could use/port. Thanks, Angel

...the tumors, and with finally, the road accidents. During these last 30 years a lot of our habits are changed: more comforts! We have learned to eat more, as consequence of the great quantity of food and medicines! We have learned to prefer softer foods, that do not tire the mastication, meats and dairy products, in spite of fruit and vegetables! We feel like wanting everything and immediately; we have learned to be outside, also for to eat! We have learned to use more always the television and the video games and to have fun being comfortably sat; we have learned to use the gyms, instead of spor...
