ggplot2中不太平滑的线,geom_smooth的替代品? [英] Less smoothed line in ggplot2, alternatives to geom_smooth?
问题描述
使用以下数据:
> str(属性)
'data.frame':431 obs。 2个变量:
$ pos:int 1 2 3 4 5 6 7 8 9 10 ...
$ att:num 0.652 0.733 0.815 1.079 0.885 ... * [介于0和3之间]
和:
ggplot(attribute,aes(x = pos,y = att))+ geom_line()+ geom_smooth()
我做了:
我想渐进地平滑黑色曲线,而不是geom_smooth默认值。我试过 n
, level
选项,但是没有按照我的意愿去做。这将是逐步增加平滑的最佳方法? (例如,一个中的平均值为2,然后在一个中尝试3,依此类推)。我想这很容易实现,但不使用 geom_smooth
,但我不知道要搜索/查找什么。谢谢。
记录在 stat_smooth
中。默认的平滑器是 loess
,并且附加的参数被传递给它,正如对 ...
论据。所以你想要什么是 span
:
ggplot(mtcars,aes( x = wt,y = mpg))+
geom_point()+
geom_smooth(span = 0.4)
此外, loess
接受度数
参数,以更好地控制平滑量。 / p>
Using the following data:
> str(attribute)
'data.frame': 431 obs. of 2 variables:
$ pos: int 1 2 3 4 5 6 7 8 9 10 ...
$ att: num 0.652 0.733 0.815 1.079 0.885 ... *[between 0 and 3]
and:
ggplot(attribute, aes(x=pos, y=att)) + geom_line() + geom_smooth()
I did:
I would like to progressively smooth the black curve, not "as much as" geom_smooth default did. I've tried n
, level
options, but didn't do what I want. Which would be the best way to increase smoothing progressively? (e.g. average 2 values in one, then try 3 in one, and so on). I guess it's something really easy or achievable without using geom_smooth
, but I don't know what to search/look for. Thanks.
This is documented in stat_smooth
. The default smoother is loess
, and additional arguments are passed on to it, as specified for the description of the ...
argument. So what you want is span
:
ggplot(mtcars,aes(x = wt,y = mpg)) +
geom_point() +
geom_smooth(span = 0.4)
Additionally, loess
accepts a degree
argument for more control over the amount of smoothing.
