plot_all_V <- ggplot(result_prod,aes(Phase,MeanACC,shape=Subtype))+ geom_point(size=2)+ geom_line()+ ylab("Porduction performance on all verbs")+xlab("Treatment phase")
Why there were no lines?
(1) I want four lines: one line for "Ba", one line for "Bei", one line for "Two-argument", and one line for "Three argument"
(2) After adding lines, how can I change the types of lines, like dashed line...?
Thank you so much!
