Hi, I would like to plot the following equation: dF(x)/dx=(k1+k2F(x))(1-F(x)) where k1 and k2 are parameters that I have estimated already. How can I plot the curve in R? Thanks! Montserrat Rue Universitat de Lleida (Spain) [[alternative HTML version deleted]]

...y, pch=19, col=2) mtext(3, text="concentration", line=2.5) Not bad, but a bit complicated for such a seemingly simple thing...also, the axes do not intersect, something I would like them to do as in the bty="l" command. I hope anyone knows a more elegant solution...

...two points (a,b). I.e. the P(a<X<b). Could anyone indicate me which is the instruction for obtain such a shadow area under a curve? I guess the solution is not difficult, but I can not find the procedure.

Hola, ¿qué tal? Sabréis que en unos días comienza un MOOC de Hastie y Tibshirani, https://class.stanford.edu/courses/HumanitiesScience/StatLearning/Winter2014/about basado en el libro "An Introduction to Statistical Learning, with Applications in R". Se me ocurre lo siguiente: 1) Montar un grupo de estudio en Madrid de manera que podamos reunirnos periodicamente (¿semanalmente?

Hello, I'm new here, but will try to be as specific and complete as possible. I'm trying to use “lm“ to first estimate parameter values from a set of calibration measurements, and then later to use those estimates to calculate another set of values with “predict.lm”. First I have a calibration dataset of absorbance values measured from standard solutions with known concentration of
