我想为明天到期的作业绘制一个带有置信区间的交互图。这是我的数据集：

interaction.plot(Snail0$water,Snail0$lightness,Snail0$total_migration)
我一直在尝试做类似ToothGrowth data底部的操作，但是显然我做错了，因为我只收到错误消息。
Snail0$water <- factor(Snail0$water)
df<-with(Snail0, aggregate(total_migration, list(lightness=lightness, water=water), mean))
df$se<-with(Snail0, aggregate(total_migration, list(lightness=lightness, water=water), function(x) sd(x)/sqrt(10)))[,3]
gp<-ggplot(df, aes(x=water, y=total_migration, colour=lightness, group=lightness))
gp+geom_line(aes(linetype=lightness)) + geom_point(aes(shape=lightness)) + geom_errorbar(aes(ymax=x+se, ymin=x-se))
错误信息：
Error: Aesthetics must either be length one, or the same length as the dataProblems:lightness, water, lightness, lightness
显然，我不知道自己在做什么，所以有人可以帮助我更正我的代码吗？
最佳答案
当使用第一个df命令创建对象aggregate时，包含因变量的列不再称为total_migration，而是x。
因此，如果在total_migration命令中将x替换为ggplot，则您的代码将起作用：
gp <- ggplot(df, aes(x=water, y=x, colour=lightness, group=lightness))
gp + geom_line(aes(linetype=lightness)) +
geom_point(aes(shape=lightness)) +
geom_errorbar(aes(ymax=x+se, ymin=x-se))
