Hello



I have a one question about random sampling matrix



I want to regeneration value of matrix

For example,

Matrix A :

1  2  3

11 12 13

21 22 23 .

sample= data.frame(a[sample(1:dim(a)[1]),sample(1:dim(a)[2])])

Then,

Matrix sample :

21 23 22

11 13 12

1  3  2



But, I want to regeneration.

Ex) Matrix sample

1      23  2

22  11  3

12  21  13



Pleases kindly help with R code!&



Thank you.

m <- matrix(c(1,21,31,2,22,23,3,23,33), nrow=3)
m

matrix(sample(m),nrow=3)

 matrix(sample(m),nrow=3)

 matrix(sample(m),nrow=3)
