I'm trying to plot a geom_rect(). Why do I receive an Error in FUN(X[[i]], ...) : object 'Month' not found? If I run df$Month in my console the object is there:
df$Month
#> [1] 2019-01 2019-02 2019-03
#> Levels: 2019-01 2019-02 2019-03
Here's my code block:
library(tidyverse)
df <- tibble(Month = factor(c("2019-01", "2019-02", "2019-03")),
Value = c(4, 9, 7))
ggplot(df, aes(Month, Value, group = 1)) +
geom_line() +
theme_minimal() +
geom_rect(data =
data.frame(xmin = min(as.integer(df$Month)) - 0.5,
xmax = max(as.integer(df$Month)) + 0.5,
ymin = min(df$Value),
ymax = max(df$Value)),
aes(xmin = xmin, xmax = xmax, ymin = ymin, ymax = ymax),
alpha = 0.2, fill = "green")
#> Error in FUN(X[[i]], ...) : object 'Month' not found
