ggplot: order of factors with duplicate levels

Question

ggplot changes the order of an axis variable, which I do not want. I know I can change the variable to a factor and specify the levels to get around this, but what if the levels

Answer 1

ggplot(df, aes(x=season2, y=temp, colour=type, group=type)) + 
   geom_point() + 
   geom_line()
