r - 如何设置 ggplot2 stat_smooth() 取值的范围以适合线条？

Question

我想让 stat_smooth 只使用指定范围内的数据来拟合一条线，换句话说，我想让 stat_smooth 拟合 x(0,99)、x(100,199) 和 x(199,299) 之间的一条线。

我设法使用 facet_grid 获得了相当接近的结果，如下所示:

ggplot(avtimes3, aes(x=trial, y=ttime, colour=factor(id))) +
facet_grid(. ~ brk, scales = "free") +
geom_vline(xintercept = short_bks, colour="red") +
geom_vline(xintercept = long_bks, colour="green") +
geom_point() + 
geom_point(shape=21, fill="white")+
opts(title=titl) +
ylab("Time taken (ms)") +
xlab("Trial No.")+
stat_smooth(method="loess") 

但它在每个网格上绘制了大量空白区域。我一直无法找到删除它的方法。

我从另一篇文章中获取的另一个部分解决方案包括为范围创建一个组，但这似乎不尊重传递给 qqplot 的因素。

ggplot(avtimes3, aes(x=trial, y=ttime, colour=factor(id))) +
geom_vline(xintercept = short_bks, colour="red") +
geom_vline(xintercept = long_bks, colour="green") +
geom_point() + 
geom_point(shape=21, fill="white")+
opts(title=titl) +
ylab("Time taken (ms)") +
xlab("Trial No.")+
stat_smooth(method="loess", aes(group=brk)) 

有关如何使其工作的任何帮助？
谢谢!

Answer 1

如果您正在谈论方面之间的空间，您可以尝试这个(另请注意，我们没有 short_brks 和 long_brks 所以我从您的示例代码中删除了它们)。 grid unit 需要功能。

require(ggplot2)
require(grid)

avtimes3$id <- factor(avtimes3$id)
## create and store plot
p <- ggplot(avtimes3, aes(x=trial, y=ttime, colour=id)) + 
  facet_grid(. ~ brk, scales = "free") + 
  geom_point(shape=21, fill="white") +
  ## remove space between panels    
  opts(panel.margin = unit(0, "lines")) + 
  ylab("Time taken (ms)") + 
  xlab("Trial No.")


## as you had
p + stat_smooth(method="loess")

## only one line per facet
p + stat_smooth(method="loess", aes(colour=NULL))

编辑:重读你写的和试过的，我想你可能想要这个:

## setup plot
p <- ggplot(avtimes3, aes(x=trial, y=ttime, colour=id)) +  
  geom_point(shape=21, fill="white") + 
  ylab("Time taken (ms)") +  
  xlab("Trial No.")

p + stat_smooth(aes(group = brk), method="loess")

这里与您之前的不同之处在于 stat_smooth 的第一个参数。是映射，第五是方法。在 R你有两个选择(也许更多)。按顺序给出参数或明确命名参数。在您的第二个示例中，您乱序提供了参数，并且没有明确命名，例如:

p + stat_smooth(method = "loess", mapping = aes(group = brk))

为每个 id 获取单独的行并按 brk 分组有点棘手(概念上)。我们需要 brk 和 id 的交互。单独着色是行不通的，就像大多数几何图形一样。

p + stat_smooth(method = "loess", mapping = aes(group = interaction(brk, id)))
