r - R stargazer，lme4和lmerTest不兼容

R新手在这里。我在使用lmerTest和stargazer时遇到问题。我正在按照本教程进行操作，以使stargazer与R中的lme4一起使用。

我运行此示例没有任何问题。

library(lme4)
library(stargazer)
data(cake)
summary(M1 <- lmer(angle ~ temp + (1 | replicate) + (1|recipe:replicate), cake, REML= FALSE))
summary(M2 <- lmer(angle ~ factor(temperature) + (1 | replicate) + (1|recipe:replicate), cake, REML= FALSE))
anova(M1,M2)
stargazer(M1, M2, style="ajps", title="An Illustrative Model Using Cake Data", dep.var.labels.include = FALSE,
          covariate.labels=c( "Temperature (Continuous)", "Temperature (Factor $<$ 185)", "Temperature (Factor $<$ 195)", "Temperature (Factor $<$ 205)", "Temperature (Factor $<$ 215)", "Temperature (Factor $<$ 225)")
)

在这种情况下，如果我包含lmerTest软件包，则stargazer将不再起作用。

library(lme4)
library(lmerTest)
library(stargazer)
data(cake)
summary(M1 <- lmer(angle ~ temp + (1 | replicate) + (1|recipe:replicate), cake, REML= FALSE))
summary(M2 <- lmer(angle ~ factor(temperature) + (1 | replicate) + (1|recipe:replicate), cake, REML= FALSE))
anova(M1,M2)
stargazer(M1, M2, style="ajps", title="An Illustrative Model Using Cake Data", dep.var.labels.include = FALSE,
          covariate.labels=c( "Temperature (Continuous)", "Temperature (Factor $<$ 185)", "Temperature (Factor $<$ 195)", "Temperature (Factor $<$ 205)", "Temperature (Factor $<$ 215)", "Temperature (Factor $<$ 225)")
)

Error in objects[[i]]$zelig.call :
  $ operator not defined for this S4 class

我真的很想使用stargazer，但是我的实验要求使用merModLmerTest对象，而stargazer不支持。有人知道解决方法吗？将merModLmerTest对象转换为兼容的lmerMod对象有多困难？

最佳答案

这是一个简单的修复。将lmerTest（位于类merModLmerTest中）的输出转换为lmerMod类。这将与观星者兼容。

class(model) <- "lmerMod"
