在R误差中绘制残差

r

在R误差中绘制残差,r,R,我试图在R中绘制拟合图，我得到以下错误： Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ 这是我的密码： exercise <- as.factor(c(10, 10, 20, 20, 10, 10, 20, 20)) time <- c("pm", "am", "am", "pm", "am", "pm", "pm", "am") glucose <- c(71.5, 10

我试图在R中绘制拟合图，我得到以下错误：

Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ
这是我的密码：

exercise <- as.factor(c(10, 10, 20, 20, 10, 10, 20, 20))
time <- c("pm", "am", "am", "pm", "am", "pm", "pm", "am")
glucose <- c(71.5, 103, 83.5, 126, 125.5, 129.5, 95, 93)

fit1 <- aov(glucose ~ exercise + time)
summary(fit1)



par(mfrow = c(2, 2))
plot(fit1)

练习你需要确保时间是一个因素


time <- as.factor(c("pm", "am", "am", "pm", "am", "pm", "pm", "am"))
