如何撤消 ggplot 数据错误代码以绘制数据？

Question

当我输入此代码时，我总是遇到同样的错误：

ggplot(exchangeGBP) + aes(Date, GBP/EUR) + geom_line(color = "deepskyblue")

错误代码：Error in FUN(X[[i]], ...) : object 'Date' not found

我应该安装软件包还是更改代码？

Answer 1

aes 之前的 + 似乎是问题所在

library(ggplot2)
ggplot(exchangeGBP, aes(Date, `GBP/EUR`)) + 
         geom_line(color = 'deepskyblue') +
         theme_bw()

set.seed(24)
exchangeGBP <- tibble(Date = seq(Sys.Date() - 10, 
      length.out = 10, by = '1 day'), `GBP/EUR` = rnorm(10))

How do I undo ggplot data error code to plot data?
