glm with binomial errors in R and GLIM
Hi all, In my continuous transition of GLIM to R I try to make a glm with binomial errors. The data file have 3 vectors: h -> the factor that is ajusted (have 3 levels) d -> number of animais alive (the response) n -> total number of animals To test proportion of alive, make d/n. In GLIM: $yvar d$ $error binomial n$ $fit +h$ scale deviance = 25.730 (change = -9.138) at cycle 4

plot survival points
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 <-

generating points over a function, its possible???
Hi, I have a new (for me) situation. I have a function for one linear model: y = 9.7909-0.035*x I have the variance of system var = 13.01403 Is possible to create a random vector points of Y (simulating the real data) over this curve using the function and the variance? I need this to a discipline. I have this: | \ | \ -> y = 9.7909-0.035*x and var = 13.014 | \ | \ | \ | \

doubt about contrib...
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

help with xyplot
Hi, I make a graphic using xyplot, it is very good. xyplot((ocorrencia/isca)~frag|especie) But I need to plot a curve for each especie's plot. I try to use panel.abline and others panel., but I dont succeed. I need to plot the function exp(a+b*x+c*x^2)/1+exp(a+b*x+c*x^2), a b and c are different for each especie.
