geom_line() によって生成されたギザギザの線を改善して、複数の点を ggplot2 の滑らかな表示可能な線に結合するプロセスはありますか?

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_line() +
geom_point()+ theme_bw()
これらのコードを使用して作成された線は、非常にピクセル化されたジグザグ線でした。より滑らかな線をプロットする方法はありますか"solid"
(ジグザグに見えません)?
