let say something like this
>a=matrix(1:25, nrow=5)
>rownames(a)=letters[1:5]
> colnames(a)=rep("A", 5)
> a
A A A A A
a 1 6 11 16 21
b 2 7 12 17 22
c 3 8 13 18 23
d 4 9 14 19 24
e 5 10 15 20 25
> b=matrix(1:40, nrow=8)
> rownames(b)=c(rep("a",4),rep("b",4))
> colnames(b)=rep("B", 5)
> b
B B B B B
a 1 9 17 25 33
a 2 10 18 26 34
a 3 11 19 27 35
a 4 12 20 28 36
b 5 13 21 29 37
b 6 14 22 30 38
b 7 15 23 31 39
b 8 16 24 32 40
as a results I wold like something like
A A A A A B B B B B
a 1 6 11 16 21 1 9 17 25 33
a 1 6 11 16 21 2 10 18 26 34
a 1 6 11 16 21 3 11 19 27 35
a 1 6 11 16 21 4 12 20 28 36
b 2 7 12 17 22 5 13 21 29 37
b 2 7 12 17 22 6 14 22 30 38
b 2 7 12 17 22 7 15 23 31 39
b 2 7 12 17 22 8 16 24 32 40
does it is clear? is there a function that automate this operation?
thank you very much!
