带ggplot的R堆积线图 [英] R stacked line graph with ggplot

问题描述

我有一个名为 m1 的数据框，与下面的相似。我想通过 agebucket 创建一个 toSL.share 的折线图，并且每个 time.period 。我正在使用 ggplot ，但是由于 agebucket 不是连续变量，所以我一直报错。

I have a dataframe called m1, similar to the one below. I want to create a line graph of toSL.share by agebucket, with a separate line for each time.period. I am using ggplot, but I keep getting an error because agebucket isn't a continuous variable.

   agebucket time.period  toSL.share

这是我要创建的代码情节：

Here's my code to create the plot:

> m1$agebucket <- as.factor(m1$agebucket)
> ggplot(m1, aes(x=agebucket, y=toSL.share, col=time.period)) + geom_line()

这是错误：

 geom_path: Each group consist of only one observation. Do you need to adjust the group aesthetic?

我不明白该错误。如何使用 ggplot 创建此图？

I don't understand the error. How can I create this graph with ggplot?

推荐答案

我部分地qplot这样：

I'm partial to qplot so:

qplot(data=m1, agebucket, toSL.share, col=time.period, geom=c('point','line'), group=time.period)

或者作为ggplot：

Alternatively as ggplot:

ggplot(data=m1, aes(agebucket, toSL.share,group=time.period))+geom_line(aes(col=time.period))
