Can you please let know if there are any packages for stochastic linear programming (SLP) in R? Thanks in advance Sudhakar Achath

...t;. In a deterministic model {i.e., transition matrix is defined as A <- matrix(c(0.70, 0.70,0.35,0.50), nrow=2,byrow=TRUE}, population growth rate can be estimated from the dominant eigenvalue {command "eigen.analysis"}. However, I cannot figure out the way to compute the asymptotic stochastic population growth rate using ?popbio?. I would like to perform a stochastic model in which my demographic rates are sampled from beta distribution with known mean and SD. For example, rather than 0.50 (4th term of my matrix), I want to sample this parameter from a beta function at each time-st...

Vegetative with Herbivory I want to read all matrices into stoch.projection( ) {popbio} Thanks for any suggestions. I could enter them all in the .txt document if I can't read them from the Excel sheet. Michelle DePrenger-Levin [[alternative HTML version deleted]]

First time user, so sorry if I don't understand protocol.. Anyway, I have created a data frame consisting of pearson's R values at various x and y coordinates and then plotted this using filled.contour. My data is similar to fMRI data except that it is a surface map reconstructed from histological sections. I like the results but would like to know how contours were detected. Google search

Hello R users, I am trying to calculate the stochastic lambda for a published matrix population model using the popbio package. Unfortunately, I have been unable to match the published results. Can anyone tell me whether this is due to slightly different methods being used, or have I gone wrong somewhere in my code? Could the answer be as sim...

Sale plano sí. Ya se que sin tener los datos y el código es un poco difícil, pero es que mis datos ocupan mucho, es imposible. Seguiré mirando por internet. Muchas gracias Rubén.
