Hi all, I have a little problem. I make an weibull survival analysis using the survival package. It,s OK, them I have the functions. I plot this funcions with curve(). I want to make a plot with the real survival points (proportion of alive x time) and them add the curves to points. I have the time to dead, the censor data and my trataments. To analysis the model is: model1 <-

Hi, I have a little doubt about contrib packages. I make some little functions in a R package format, this functions are for my personal use (envelopes for glm models and a plot bar routine). Some friends ask me about the liberation of this functions in a web site, R contrib etc. what is the correct procedure for send a package to R contrib? The functions is not create for me, is adaptaded to R

Hi, I have make an analise with presence and absence, y=(1 e 0). I have a area continuous data and a sp data with 25 levels. I have 300 points. When I make glm((presenca/peso)~area,weights=peso,family=binomial,maxit=1000) where presenca is 0 or 1. peso is the unit = 1. area is the continuous data. The analysis is OK. When I put the sp and interactions in analysis this warning appear.
