How to improve jagged line graph in ggplot2?

Question

Is their any process to improve jagged lines produced by geom_line() joining multiple points into smooth presentable lines in ggplot2?

     lai.se <- structu         


        

Answer 1

I'm guessing you're trying to smooth a line. Is this in the ball park of what you're after?

ggplot(lai.se, aes(x=DAS, y=LAI, colour=DOS)) + 
  geom_errorbar(aes(ymin=LAI-se, ymax=LAI+se), colour ="black", size =.5, width=1, position=position_dodge(.9)) +
  geom_smooth() +
  geom_point()+ theme_bw()
