Hi R,
I have a matrix,
> x1=matrix(NA,6,6,dimnames=list(letters[1:6],LETTERS[1:6]))
> x1
A B C D E F
a NA NA NA NA NA NA
b NA NA NA NA NA NA
c NA NA NA NA NA NA
d NA NA NA NA NA NA
e NA NA NA NA NA NA
f NA NA NA NA NA NA
> x2=matrix(rpois(9,1),3,3,dimnames=list(c("b","a","f"),c("D","E","F")))
> x2
D E F
b 0 3 0
a 2 2 1
f 1 0 0
I need to put the values of x2 in the corresponding elements of x1. So
then, x1 would look like:
A B C D E F
a NA NA NA 2 2 1
b NA NA NA 0 3 0
c NA NA NA NA NA NA
d NA NA NA NA NA NA
e NA NA NA NA NA NA
f NA NA NA 1 0 0
What would be the best way to do this?
Many Thanks,
Shubha
