使用 ggplot2 函数的混合效应模型残差图

Question

我正在尝试使用 ggplot2 函数绘制混合效应模型的残余效应。但是，在执行搜索后，我发现了一些可用的函数，但在我看来，对于函数 nlme，它们不起作用。

我打算制作的图表是以下示例中的图表：

数据在这里。

我最初尝试的计算例程如下，查看在 ggplot2 中执行函数时出现的错误。

self.clearButton.bind(on_release=lambda a: self.clearBox())

我尝试制作图表的另一种方法是使用下面的函数，但我没有成功。

library(splines)
library(ggplot2)
library(nlme)
library(gridExtra)

setwd("C:\\Users\\Desktop")
datanew1 = read.table("dadosnew.csv", header = T, sep=";", dec = ",")
datanew1$DummyVariable = as.factor(datanew1$DummyVariable)
datanew1$Variable2 = as.factor(datanew1$Variable2)
datanew1$Variable3 = as.factor(datanew1$Variable3)

model <-  lme(Response~(bs(Variable1, df=3)) + DummyVariable,
                         random=~1|Variable2/Variable3, datanew1, method="REML")
completemodel <- update(model, weights = varIdent(form=~1|DummyVariable))

p1 <- qplot(.fitted, .resid, data = completemodel) +
  geom_hline(yintercept = 0) +
  geom_smooth(se = FALSE)

Erro: `data` must be a data frame, or other object coercible by `fortify()`, not an S3 object with class lme
Run `rlang::last_error()` to see where the error occurred.

p2 <- qplot(sample =.stdresid, data = completemodel, stat = "qq") + geom_abline()
grid.arrange(p1,p2)

Além disso: Warning message:
`stat` is deprecated
