[R] getting confidence intervals after lm fitting

Hi, After fitting with lm, I want to get the 95 % confidence intervals of the expected predicted value. I know in S-plus I can use pointwise() to get the confidence intervals . But in R, I couldn't find such a function. Is there any R package available for such functionalities. Please advise. t

[R] regression to get non-negative parameters

Hi, I am working on a model sort of like a credit assignment problem. The goal is to get non-negative weights for each input variable and discount the predictors (down to 0) that lead to no credits. I am trying out the lm fitting and find out they give a lot of negative weights. I am totally s

[R] ANOVA procedure on the sufficient statistics

Hi, I have a two-way anova with unequal cell numbers that I want to analyze. The problem is I don't have individual observations of the data. I only have the sufficient statistics (mean, variance, # of observations) for each cell. Is there any existing function in S-plus that would allow me to

[R] SSfpl question

Hi, I am trying to do a nls fitting using the SSfpl self-restart function but I got an error like the following: > nls.2 <- nls(map.rr ~ SSfpl(mail.pv, phi1, phi2, phi3, phi4), data=pv.rr.200) Error in nls(y ~ cbind(1, 1/(1 + exp((xmid - x)/exp(lscal, data = xy, : step factor 0.0004
