Question

我是一个泡菜。我有多个矩阵，并希望通过前一个矩阵的最后一列对矩阵的第一列进行排序。有任何想法吗？我尝试过申请，订购，排序等等。

  five<-matrix(c(5555,1113,1112,1111,2222,1212,9999,8888),4,2);

  #######order all data######################
  onea<-one[order(one[,2]),];
  twoa<-two[order(two[,1]),];
  threea<-three[order(twoa[,2]),]; ####CANT GET THIS PART TO WORK!!!!!

我想要做的是按两个[，2]

排序

  ####output looking for: 
 cbind(onea,twoa,threea)

 [1,] 2004 12345 12345 7777 7777 6789
 [2,] 2001 23456 23456 3456 3456 5677
 [3,] 2002 23567 23567 2345 2345 6678
 [4,] 2003 54321 54321 1234 1234 6767

目前还不清楚你究竟在追求什么，但如果你正在寻找每个矩阵的最后一列与下一个矩阵的第一列“匹配”，你可以将order和{{1}结合起来像这样：

rank

用R中的另一个矩阵从一个矩阵中排序数据
