Hi R,
I have a list of matrices. I need to get the sum of all the matrices in
the list.
Example:
a=b=c=d=matrix(1:4,2,2)
l=list(a,b,c,d)
I need:
> a+b+c+d
[,1] [,2]
[1,] 4 12
[2,] 8 16
Something like do.call("+",l) is not working...why is this?
I may not be knowing the number of matrices in the list...
Thanks, Shubha
