我认为这是一个新引入的错误。它至少会破坏以前正在运行的代码。
library(glmmADMB)
epil2$subject <- factor(epil2$subject)
fm <- glmmadmb(y~Base*trt+Age+Visit+(Visit|subject),
data=epil2, family="nbinom")
VarCorr(fm)
产生以下错误:
Error in glmmADMB::VarCorr(fm) :
could not find symbol "rdig" in environment of the generic function
来自VarCorr
的 nlme
仍可正常使用:
library(nlme)
nlme::VarCorr(fm) ##WORKS
glmmADMB::VarCorr(fm) ##Still doesn't work.
如果有帮助,这是我的systemInfo:

答案 0 :(得分:4)
我找到了解决问题的方法。我使用了这里提供的安装代码:
http://glmmadmb.r-forge.r-project.org/。我不确定是否有必要,但在运行以下代码之前,我导航到我的~R/R-3.2.3/library
文件夹并删除了glmmADMB文件夹。
然后我运行了下面的代码。
install.packages("R2admb")
install.packages("glmmADMB",
repos=c("http://glmmadmb.r-forge.r-project.org/repos",
getOption("repos")),
type="source")
这将我的glmmADMB更新为版本0.8.3.3,更正了错误(将其变为警告)。
