问题描述
我有一个到目前为止运行良好的代码。我想用 gls、lme 和 gamm（来自包 nlme 和 mgcv）测试东西，我用 anova() 比较了不同的模型。但是，我需要另一个包，它不适用于我的 R 版本（已使用近一年）。因此，我更新了 R（通过 updater 包）和 RStudio。
现在的问题是，anova() 在运行后不提供任何输出，或者只提供“Denom. DF: 91”而没有其他任何输出。
现在我尝试了不同的方法并进行了大量搜索，但我发现当前没有解决此类问题的威胁，而查看帮助文件时只是说，它应该像我使用的那样工作。因此，我怀疑我错过了一些重要的东西（甚至可能很明显），但我不明白。我希望你能告诉我我哪里做错了。
这里有一些数据可以玩（从txt文件复制）：

这基本上是我尝试运行的模型之一：
test <- read.table(file="C:/Users/marvi_000/Desktop/testdata.txt")
str(test)
test$treat <- as.factor(test$treat)
test$nest <- as.factor(test$nest)
library(nlme)
m.test <- gls(x ~ treat * time,correlation = corAR1(form =~ time | nest),test,na.action = na.omit)
anova(m.test)
输出为：
德诺姆。 DF：91
将模型与 nova(m1,m2) 进行比较时，什么也没有发生。
当我从包 gamm 运行 mgcv 并使用 anova(m$lme) 或 anova(m1$lme,m2$lme) 时，情况也是如此。
我会很感激任何帮助或提示，为我指明正确的方向。非常感谢！
编辑：
经过一番讨论，我发现这是脚本的问题。我正在使用 RStudio 和 RMarkdown。但是，当我在降价脚本中运行代码（使用 cntrl+enter，逐行）时，anova(lmemodel) 命令无法正常工作。但是，如果我只是将这个单个命令复制到平面 r 脚本中（仍然使用当前环境），则该命令会正确执行并显示所需的输出。
我不知道那里发生了什么。如果有人知道问题出在哪里，或者如何解决它，我仍然很乐意听到。
