IN r，如何将摘要组合在一起

问题描述

假设我有 5 组数据的 5 个摘要.我怎样才能得到这些数字或将摘要合并为 1 而不是 5

say i have 5 summary for 5 sets of data. how can i get those number out or combine the summary in to 1 rather than 5

       V1               V2               V3               V4
 Min.   : 670.2   Min.   : 682.3   Min.   : 690.7   Min.   : 637.6
 1st Qu.: 739.9   1st Qu.: 737.2   1st Qu.: 707.7   1st Qu.: 690.7
 Median : 838.6   Median : 798.6   Median : 748.3   Median : 748.3
 Mean   : 886.7   Mean   : 871.0   Mean   : 869.6   Mean   : 865.4
 3rd Qu.:1076.8   3rd Qu.:1027.6   3rd Qu.:1070.0   3rd Qu.: 960.8
 Max.   :1107.8   Max.   :1109.3   Max.   :1131.3   Max.   :1289.6
       V5
 Min.   : 637.6
 1st Qu.: 690.7
 Median : 748.3
 Mean   : 924.3
 3rd Qu.: 960.8
 Max.   :1584.3

我怎么能有一张桌子看起来像

how can i have 1 table looks like

        v1  v2 v3 v4 v5
  Min.   :
 1st Qu.:
 Median :
 Mean   :
 3rd Qu.:
 Max.   :

或者如何将这些数字保存为向量，以便我可以使用矩阵生成表格

or how to save those number as vector so i can use matrix to generate a table

推荐答案

看起来您的数据位于数据框或矩阵中.如果是这样，您可以执行以下操作:

It looks like your data is in a data frame or matrix. If so, you can do the following:

> df <- data.frame(a=1:50, b=3:52, c=rnorm(500))
> apply(df, 2, summary)
           a    b         c
Min.     1.0  3.0 -3.724000
1st Qu. 13.0 15.0 -0.733000
Median  25.5 27.5 -0.004868
Mean    25.5 27.5 -0.033950
3rd Qu. 38.0 40.0  0.580800
Max.    50.0 52.0  2.844000
