How to remove y-axis labels in ggplot

To remove y-axis labels in a ggplot chart, you can use the element_blank() function for the axis.text.y parameter. Here’s an example code:

library(ggplot2)

# create example data
df <- data.frame(x = 1:10, y = rnorm(10))

# create ggplot chart
ggplot(df, aes(x, y)) +
  geom_point() +
  theme(axis.text.y = element_blank())

This will remove the y-axis labels, but keep the y-axis line and ticks. If you also want to remove the ticks, you can use the element_blank() function for the axis.ticks.y parameter:

ggplot(df, aes(x, y)) +
  geom_point() +
  theme(axis.text.y = element_blank(), 
        axis.ticks.y = element_blank())

This will remove both the y-axis labels and ticks.
