如何使用ggpairs在GGally中绘制黄土估计？ [英] How to draw loess estimation in GGally using ggpairs?

问题描述

我尝试了GGally包装一点点。特别是ggpairs功能。但是，当情节平滑时，我不知道如何使用黄土而不是lm。有任何想法吗？
这里是我的代码：

  require（GGally）
 diamonds.samp<  -  diamonds [sample （1：dim（diamonds）[1]，200），] 
 ggpairs（diamonds.samp [，c（1,5）]，
 lower = list（continuous =smooth），
 params = c（method =loess），
 axisLabels =show）
  

谢谢！

PS与plotmatrix函数相比，ggpairs要慢得多......因此，大多数情况下，我只是使用ggplot2的plotmatrix。 解决方案 div>

那么文档没有说，所以使用源代码Luke

1. 您可以更深入地了解源代码：
   
   

   ls（'package：GGally'）

   
   
   

   GGally :: ggpairs

   
   
   

   。 ..并浏览它引用的每个函数...

   
   
   

   好像args被映射到ggpairsPlots然后 - >然后调用plotMatrix

   
   
   

   因此，显然选择平滑器并不明确支持，您只能选择 continuous =smooth 。如果它的行为类似于 ggplot2：geom_smooth ，它会在内部自动计算出哪些支持的平滑器要调用（对于< 1000数据点，gam for> = 1000）。
   您可能想要通过调试器来查看情节内发生了什么。

I tried GGally package a little bit. Especially the ggpairs function. However, I cannot figure out how to use loess instead of lm when plot smooth. Any ideas? Here is my code:

require(GGally)
diamonds.samp <- diamonds[sample(1:dim(diamonds)[1],200),]
ggpairs(diamonds.samp[,c(1,5)], 
        lower = list(continuous = "smooth"),
        params = c(method = "loess"),
        axisLabels = "show")

Thanks!

P.S. compare with the plotmatrix function, ggpairs is much much slower... As a result, most of the time, I just use plotmatrix from ggplot2.

解决方案

Well the documentation doesn't say, so use the source, Luke

1. You can dig deeper into the source with:

   ls('package:GGally')

   GGally::ggpairs

   ... and browse every function it references ...

   seems like the args get mapped into ggpairsPlots and then -> plotMatrix which then gets called

   So apparently selecting smoother is not explicitly supported, you can only select continuous = "smooth". If it behaves like ggplot2:geom_smooth it internally automatically figures out which of the supported smoothers to call (loess for <1000 datapoints, gam for >=1000). You might like to step it through the debugger to see what's happening inside your plot. I tried to follow the source but my eyes glaze over.

or 2. Browse on https://github.com/ggobi/ggally/blob/master/R/ggpairs.r [4/14/2013]
