Thank you very much, David;
for row swapping: R2<==>R3

> A=diag(1:4)
> A
     [,1] [,2] [,3] [,4]
[1,]    1    0    0    0
[2,]    0    2    0    0
[3,]    0    0    3    0
[4,]    0    0    0    4
> A1=A[c(1,3,2,4),]
> A1
     [,1] [,2] [,3] [,4]
[1,]    1    0    0    0
[2,]    0    0    3    0
[3,]    0    2    0    0
