【问题描述】:
我正在使用这个:
http://www.cookbook-r.com/Graphs/Plotting_means_and_error_bars_(ggplot2)/
通过对数据框中的数据进行分组来绘制多个折线图的教程。数据如下所示:
> all
y x err lab
1 -41.93 5.7696373 0.9120865 he
2 -41.68 5.6345447 0.9100468 he
3 -41.43 5.4954702 0.9068282 he
4 -41.18 5.3588358 0.9054044 he
...
471 15.72 4.3701857 0.5170079 te
472 15.97 4.5128508 0.5262806 te
473 16.22 4.6592179 0.5320847 te
474 16.47 4.8052565 0.5397946 te
475 16.72 4.9518592 0.5465613 te
476 16.97 5.1057900 0.5504546 te
477 17.22 5.2503157 0.5602737 te
478 17.47 5.4000783 0.5711784 te
479 17.72 5.5506885 0.5830945 te
480 17.97 5.7085180 0.6109026 te
我正在使用下面的线来绘制图表:
ggplot(all, aes(x,y, colour=lab, group=lab)) + geom_errorbarh(aes(xmin=x-err, xmax=x+err)) + geom_line() + geom_point()
我得到的如下:
我只想修复删除垂直线。它们应该看起来有两条单独的线(每种颜色),并带有自己的水平误差线。
我应该在 ggplot 函数中更正什么? 非常感谢!

只是不要使用
geom_line?
