根据R语言数据集airquality，绘制密度图，分页折线图，散点拟合图，带点箱型图

好的，以下是你所需要的代码：

绘制密度图：

# 导入数据
data(airquality) 
# 绘制密度图
densityplot(~ Ozone, data = airquality, main = "Ozone Density Plot")

分页折线图：

# 导入数据
data(airquality)
# 绘制分页折线图
xyplot(Ozone~ Day | Month, data = airquality, type = "l", main = "Ozone Levels by Month")

散点拟合图：

# 导入数据
data(airquality) 
# 绘制散点图
plot(Wind, Ozone, main = "Wind and Ozone Levels", xlab = "Wind", ylab = "Ozone")
# 添加拟合线
fit <- lm(Ozone ~ Wind, airquality) 
abline(fit, col = "red")

带点箱型图：

# 导入数据
data(airquality) 
# 绘制带点箱型图
bwplot(Ozone ~ Month, data = airquality, main = "Ozone Levels by Month", xlab = "Month", ylab = "Ozone", col = "lightblue")
stripchart(Ozone ~ Month, data = airquality, method = "jitter", pch = 20, add = TRUE)

希望这些代码对您有所帮助！
