用ggplot绘制表对象? [英] Plot table objects with ggplot?

问题描述

我有以下数据:

         No    Yes
Female  411   130
Male    435   124

使用标准表命令创建的

.现在，使用图可以这样绘制:

which was created using the standard table command. Now with plot I can plot this as such:

plot(table(df$gender, df$fraud))

，然后输出2x2条形图.

and it then outputs a 2x2 bar chart.

所以我的问题是，如何使用ggplot2做到这一点?有没有办法将表对象转换为数据框?我会这样做，但是这变得一团糟，然后您需要重命名列和行标题，而这实际上只是一件很简单的事情而变成一团糟?

So my question is, how can I do this with ggplot2? Is there any way with out transforming the table-object to a data frame? I would do that, but it becomes a mess and you then need to rename column and row headers and it just becomes a mess for what is really a quite simple thing?

推荐答案

诸如

ggplot(as.data.frame(table(df)), aes(x=gender, y = Freq, fill=fraud)) + 
    geom_bar(stat="identity")

以最少的重新标记次数获得相似的图表.

gets a similar chart with a minimum amount of relabelling.
