来自箱线图中data.frame的保留订单 [英] Retained order from data.frame in boxplot

问题描述

我有一个data.frame包含有序数据.当我将其绘制在箱线图中时，它会自动按照箱线图的字母顺序进行排序.

I have a data.frame containing ordered data. When I plot it in the boxplot, it automatically sort by alphabetical order by boxplot.

有没有办法在绘图的data.frame中保留顺序?

Is there a way to retain the order in the data.frame in the plotting?

data.frame(按日期排序):

data.frame (ordered by Date) :

  Date       ID         Rate         Label
20131103    54232        98        54232 20131103
20131223    32123        94        32123 20131223
20140101    12345        89        12345 20140101

箱线图:

boxplot(data_set$Rate ~ data_set$Label,
        data=data_set,
        col="yellow",
        main=Rate Trend,
        las=2, pch=0, outcol="red",
        par(mar = c(12, 5, 4, 2)+ 0.1))

在代码上方，自动按ID对数据进行排序，而不是使用data.frame中的顺序.有没有办法在boxplot中的data.frame中保留顺序?我正在使用R v2.12.2.

Above code, automatically sort the data by ID instead of using the order in the data.frame. Is there a way to retain the order in the data.frame in boxplot? I am using R v2.12.2.

谢谢您的帮助.

推荐答案

这是由于要素Label级别的顺序所致.一种可能性:

it is due to the order of the levels of the factor Label. One possibiliy:

with(data_set, boxplot(Rate ~ factor(Label, levels=unique(Label)), 
    col="yellow",
    main="Rate Trend",
    las=2, pch=0, outcol="red",
    par(mar = c(12, 5, 4, 2)+ 0.1)))
