How do I change the formatting of numbers on an axis with ggplot?

Question

I\'m using R and ggplot to draw a scatterplot of some data, all is fine except that the numbers on the y-axis are coming out with computer style exponent formatting, i.e. 4e

Answer 1

Another option is to format your axis tick labels with commas is by using the package scales, and add

 scale_y_continuous(name="Fluorescent intensity/arbitrary units", labels = comma)

to your ggplot statement.

If you don't want to load the package, use:

scale_y_continuous(name="Fluorescent intensity/arbitrary units", labels = scales::comma)
