散点图:针对一个 Y 绘制多个单独的 X [英] Scatterplot: multiple individual Xs plotted against one Y

问题描述

我有一个预测变量 Y 和许多 X.我想针对 Y 绘制所有 X，您将如何使用对()，但我不想看到每个组合的矩阵.

I have one predictor variable, Y, and many Xs. I would like to plot all of the Xs against the Y, how you would using pairs(), but I do not want to see the matrix of every combination.

我只想看到一个 Y 行和 X 列或一个 Y 列和 X 行.任何帮助将不胜感激.

I just want to see one Y row and X columns or one Y column and X rows. Any help would be appreciated.

推荐答案

假设您的数据是 mtcars(内置)并且您的一个预测器是 mpg:

Let's say your data is mtcars (built-in) and your one predictor is mpg:

library(ggplot2)
library(reshape2)
mtmelt <- melt(mtcars, id = "mpg")

ggplot(mtmelt, aes(x = value, y = mpg)) +
    facet_wrap(~variable, scales = "free") +
    geom_point()

这很不寻常，更常见的是您将预测变量放在 x 轴上，但这正是您所要求的.

This is pretty unusual, more commonly you put predictors on the x-axis, but it's what you asked for.
