similar to: more in contour plot for non-linear models

Hello all, I've tried to reproduce the contour plot that appears in the book of Venables and Ripley, at page 255. Is a F-statistic surface and a confidence region for the regression parameters of a non-linear model. It uses the stormer data that are in the MASS package. I haven't been able to reproduce the plot either in R ( version 1.5 ) and S. It makes the axes and it puts the

Hi, I know that it is possible to use C++ functions under the R environment. In any case my intention is the opposite way: use R functions like "glm" or "lm" in my C++ code. How should I deal with this problem?

Hi everybody, Working with interval censored data using S+, I often use the survival analysis' functions kaplanMeier() and censorReg(). Does anybody know, whether these functions exist in R, too? Thanks in advance for any answer! Saludos, Klaus. ---------------------------------------------------- Klaus Langohr Departament d?Estad?stica i Investigaci? Operativa Universitat Polit?cnica de

Hello, I would like to insert S code to my latex document. I was looking for a listings package that supports S. In www.r-project.or in the software/other section there is an item with a link to latex package listings, but it seems that the link is broken. Does anybody know an alternative to get the package? Thanks in advance,

Hello, Do you know if it's possible to create a plot as in matlab with the options hold on and hold off? For example I want to plot in the same figure the theoric cdf of the normal distribution and the empiric cdf from the raw data. Thank you, Josep.

Hi everyone, I am doing 5 years mortality predictive index score with survival analysis using a Cox proportional hazard model where I have a continous predictive variable and a right censored response which is the mortality, and the individuals were followed a maximum of 7 years. I'd like to asses the discrimination ability of survival analysis Cox model by computing a ROC curve and area
