我尝试使用ggplot绘制预先计算的置信区间。
但是有一个问题：
library(ggplot2)
p = ggplot(rawHistoricValues,aes(x=date,y=cumsum(amount)))+geom_line(color = "steelblue")
p + geom_ribbon(data=predictions, aes(ymin=pct05, ymax=pct95)) + geom_ribbon(data=predictions, aes(ymin=pct25, ymax=pct75))
此代码导致错误：Objekt 'amount' not found。奇怪的是，绘制历史数据的第一个命令确实使用amount并且正确绘制它并且只有geom_ribbon似乎有问题
这是数据集的一部分
date pct05 pct25 pct50 pct75 pct95 group
