"there is no package called" 安装 sjPlot 时出错

"there is no package called" error during installation of sjPlot

library("sjPlot", lib.loc="~/R/win-library/3.2")
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
there is no package called ‘pbkrtest’
Error: package or namespace load failed for ‘sjPlot’
> sjp.lmer(fitted2, type = "fe")
Error: could not find function "sjp.lmer"

我已经安装了这个包,所以有谁知道为什么我在输入以下代码后会出现上面的错误消息?谢谢

library(lme4)
sjp.lmer(fitted2, type = "fe")

看起来包 pbkrtest 丢失了,这是 sjPlot.

使用的一些包的依赖项
