如何修复geom_rect中的层错误

发布于01月16日

在使用geom_rect创建gggraph图表时，我遇到以下错误:

Error in `geom_rect()`:
! Problem while computing aesthetics.
ℹ Error occurred in the 1st layer.
Caused by error in `FUN()`:
! object 'Weekly_Sales' not found

我的代码是:

ggplot(data = df1, aes(x = Date, y = Weekly_Sales)) +
  geom_rect(data = df2, color = 'white',aes(xmin = as.Date(xmin), 
  ymin = ymin, xmax = as.Date(xmax), ymax = ymax, fill = changes),alpha = .4) +
  geom_line(color = 'orange', size = 1.25) + 
  scale_fill_manual(values = c('blue', 'green'))

Weekly_Sales列位于df1数据集中.

推荐答案

你需要在geom_rect里面加inherit.aes = F.

inherit.aes
If FALSE, overrides the default aesthetics, rather than combining with them.

ggplot(data = df1, aes(x = Date, y = Weekly_Sales)) +
  geom_rect(data = df2, inherit.aes = F, color = 'white',aes(xmin = as.Date(xmin), 
  ymin = ymin, xmax = as.Date(xmax), ymax = ymax, fill = changes),alpha = .4) +
  geom_line(color = 'orange', size = 1.25) + 
  scale_fill_manual(values = c('blue', 'green'))
