R How to Show the Y-Axis of a ggplot2 Barplot in Percentage Points (Example Code)

my_df <- data.frame(labels = c("L1", "L2", "L3"),             # Example data
                    percentages = c(0.8, 0.4, 0.5))
my_df                                                         # Print data
#   labels percentages
# 1     L1         0.8
# 2     L2         0.4
# 3     L3         0.5

my_df <- data.frame(labels = c("L1", "L2", "L3"), # Example data percentages = c(0.8, 0.4, 0.5)) my_df # Print data # labels percentages # 1 L1 0.8 # 2 L2 0.4 # 3 L3 0.5
