Change the thousands separator in a ggplot

r ggplot2 decimal scale separator

p + scale_y_continuous(labels=function(x) format(x, big.mark = ".", scientific = FALSE))

r ggplot2 decimal scale separator

this also works:

p + scale_y_continuous(labels = scales::comma)

r ggplot2 decimal scale separator

Very good answer. As you are defining a thousands separator, it is better to also define the decimal separator as a comma, to avoid errors.

p + scale_y_continuous(labels=function(x) format(x, big.mark = ".", decimal.mark = ",", scientific = FALSE))
