的R - 爲固定值添加隨機值未在列重複矩陣和行

Question

及彼很大的幫助，隨機矩陣沒有重複的行和列（Fixed values not repeated over column and row）我有一個關於修改另一個問題之後。

所以，先下手做了什麼：我想與隨機的行和列的矩陣無需在每個重複（行方向和列）明智的。再次感謝這裏本有很大的幫助是jdobres代碼（https://stackoverflow.com/users/6436545/jdobres）我最終使用：

# number of rows and columns 
n <- 10 

# create ordered rows and columns 
ordered.by.row <- matrix(1:n, n, n) 
ordered.by.col <- matrix(1:n, n, n, byrow = T) 

# offset the rows and columns relative to each other. 
# no row or column has a repeated value, but the values are still ordered 
offset <- (ordered.by.row + ordered.by.col) %% n + 1 

# shuffle the columns, then shuffle the rows, this produces a randomized matrix 
# 'shuffle.row' is the final, randomized matrix 
set.seed(1222) # change this to change randomization 
shuffle.col <- offset[,sample(1:n, n, replace = F)] 
shuffle.row <- shuffle.col[sample(1:n, n, replace = F), ] 

# verify solution 
any(apply(shuffle.row, 1, function(r)any(duplicated(r)))) # FALSE 
any(apply(shuffle.row, 2, function(r)any(duplicated(r)))) # FALSE 


> # create ordered rows and columns 
ordered.by.row <- matrix(1:n, n, n) 
ordered.by.col <- matrix(1:n, n, n, byrow = T) 

# offset the rows and columns relative to each other. 
# no row or column has a repeated value, but the values are still ordered 
offset <- (ordered.by.row + ordered.by.col) %% n + 1 

# shuffle the columns, then shuffle the rows, this produces a randomized matrix 
# 'shuffle.row' is the final, randomized matrix 
set.seed(1222) # change this to change randomization 
shuffle.col <- offset[,sample(1:n, n, replace = F)] 
shuffle.row <- shuffle.col[sample(1:n, n, replace = F), ] 

# verify solution 
any(apply(shuffle.row, 1, function(r)any(duplicated(r)))) # FALSE 
any(apply(shuffle.row, 2, function(r)any(duplicated(r)))) # FALSE 

     [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] 
[1,] 1 10 6 9 2 8 3 5 7  4 
[2,] 3 2 8 1 4 10 5 7 9  6 
[3,] 7 6 2 5 8 4 9 1 3 10 
[4,] 9 8 4 7 10 6 1 3 5  2 
[5,] 10 9 5 8 1 7 2 4 6  3 
[6,] 2 1 7 10 3 9 4 6 8  5 
[7,] 8 7 3 6 9 5 10 2 4  1 
[8,] 6 5 1 4 7 3 8 10 2  9 
[9,] 5 4 10 3 6 2 7 9 1  8 
[10,] 4 3 9 2 5 1 6 8 10  7 

但是我現在，我想我的第一行有問題（可以說排1,2,3）按特定順序修復。不過，我需要新的行4至10再次隨機分組並沒有（關於1-3行也沒有重複）重複！

所以，比如我有3行是這樣的：

 [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] 
[1,] 8 7 3 6 9 5 10 2 4  1 
[2,] 6 5 1 4 7 3 8 10 2  9 
[3,] 5 4 10 3 6 2 7 9 1  8 

但接下來的7行我想隨機但不重複（在任何行或列）值，而不改變第一行...

任何想法？我無法弄清楚如何排除那些我想留下來（第1-3行），但仍然沒有在其他行和列的重複...

您的幫助將再次非常感謝！

編輯：

非常感謝您Moody_Mudskipper您的幫助！這是什麼解決方案看起來就像用我的（假的）數據：

mat<-as.matrix(first.rows) 
nkeep <- 3 
mat_shuffled <- mat[c(1:nkeep,sample((nkeep+1):nrow(mat),replace=FALSE)),] 

    [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] 
row1 1 4 7 6 5 3 2 8 9 10 
row2 10 7 3 2 1 4 5 9 8  6 
row3 9 2 4 3 5 7 10 1 6  5 
     10 7 9 6 8 2 5 4 3  1 
     1 10 8 4 7 3 5 2 6  9 
     10 6 4 1 8 3 7 2 5  9 
     2 5 7 8 9 6 1 3 4 10 
     2 1 10 4 8 9 3 6 5  7 
     8 5 3 2 4 1 10 7 6  9 
     6 1 5 4 2 10 3 8 7  9 

還得感謝你！

將這項工作？

mat <- matrix(1:100,10) 
nkeep <- 3 
mat_shuffled <- mat[c(1:nkeep,sample((nkeep+1):nrow(mat),replace=FALSE)),]
