Hello, basic beginner here.
I'm trying out different graphics in R and I made this scatter plot for Temperature and Solar Radiation using the basic airquality dataset. I thought it would be useful to visualise which points related to which month, however as they used numbers rather than names, the scale for the colour is continuous and I get a graduated colour palette rather than 5 distinct colours.
ggplot(airquality, aes(x=Temp, y=Solar.R))+
Is there a way of assigning the numbers in the "Month" column to a specific name (ie 5="May") and then mapping that to a colour?
