...hanks for the help. I have a reason to continue with R-3.0.3.

I downloaded https://cran-archive.r-project.org/bin/windows/contrib/3.0/aod_1.3.zip and installed the zip file, which worked in both RStudio and R (without RStudio).

I wonder if you are perhaps trying to solve the wrong problem. If you like what the older version of the aod package does, but not the current version, then I think the solution is to propose an option to the aod maintainer that would restore your preferred algorithm into the current version, and then use the current R. A less good, but possibly workable, option is to compile the old version of aod into...

Dear all, I found a problem with 'lme4'. Basically, once you load the package 'aod' (Analysis of Overdispersed Data), the functions 'lmer' and 'glmer' don't work anymore: library(lme4) (fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)) (gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd), family = binomial,...

...lder version of (R-3.0.3) for a reason. While installing a package from CRAN (either in RStudio or R), I received the following warning message saying unable to access index for repository http://cran.rstudio.com/bin/windows/contrib/3.0.

Then you'd rather need install.packages("aod",repos='https://cran-archive.r-project.org') or use the contrib.url argument.

Hi, When modeling with negbin from the aod package, parameters for a given count y | lambda~Poisson(lambda) with lambda following a Gamma distribution Gamma(r, theta) are estimated. The intercept is called phi. Some other parameters may be also be estimated from factors in the data: the estimates returned for all these would be in accord...
