r - 绘制残差（连续）与解释变量（分类）警告：“在 xy.coords(x, y, xlabel, ylabel, log) 中：强制引入的 NAs”

问题描述

长时间的googler，第一次提问，如果我的问题格式不是很好，对不起。

我有一个名为 daily 的小标题，这是 dput 输出：

structure(list(Moon_Phase = c("mid", "mid", "mid", "mid", "mid", 
"new", "new", "new", "new", "new", "new", "new", "new", "new", 
"new", "new", "new", "new", "new", "new", "new", "new", "new", 
"new", "new", "new"), name = c("Al_Capone", "Al_Capone", "Bonnie", 
"Clyde", "Clyde", "Al_Capone", "Al_Capone", "Barb", "Barb", "Biggie", 
"Biggie", "Bonnie", "Bowser", "Bowser", "Doe", "Doe", "Jesse", 
"Jesse", "Lizzie", "Lizzie", "Louise", "Louise", "Roxy", "Roxy", 
"Sue", "Sue"), `date(DateTime)` = structure(c(17215, 17216, 17156, 
17155, 17156, 17133, 17134, 17161, 17162, 17157, 17158, 17156, 
17216, 17217, 17199, 17200, 17161, 17162, 17185, 17186, 17133, 
17134, 17196, 17197, 17193, 17194), class = "Date"), count = c(60970.2127659574,

0.138869248196884, 0.137792634329098, 0.15698540693065)), class = c("grouped_df", 
"tbl_df", "tbl", "data.frame"), row.names = c(NA, -26L), vars = c("Moon_Phase", 
"name"), drop = TRUE)

我创建了一个线性模型：

m0 <- lm(count ~ Moon_Phase, data = daily)

我想检查我的模型的独立性，所以我绘制了残差与解释变量：

plot(x = daily$Moon_Phase,
     y = E1,
     xlab = "Moon Phase",
     ylab = "Normalized residuals",
     xlim = c(0,nrow(daily))
)

我还想检查是否需要包含 daily$name 作为随机效应，因此我将无随机效应线性模型的残差与潜在随机效应进行了比较：

lm.test <- lm(count ~ Moon_Phase, data = daily)
lm.test.resid <- rstandard(lm.test)

并绘制：

plot(lm.test.resid ~ daily$name, 
     xlab = "Name",
     ylab = "Standardized residuals",
     xlim = c(0,nrow(daily)))

每次我使用 plot() 时，都会收到以下警告消息：

警告消息：在 xy.coords(x, y, xlabel, ylabel, log) 中：强制引入的 NA

有谁知道为什么会出现该消息？我在这里和其他论坛上看到其他人遇到过这个问题，并且将事物转换为因子和/或数字似乎对其他人有帮助，所以我尝试了as.numeric(E1),as.factor(daily$Moon_Phase)和as.factor(daily$name)，但这似乎没有帮助。

谢谢！
