[R] Arithmetic on multiple files

[Muhammad Rahiz]

Dear R-users,

I'd like to perform arithmetic functions on 1000 files containing a 
2000x2000 matrix. Can anyone advise?

For example,

File1            File2           Output
1 1 1           4 4 4           5 5 5
2 2 2     +    5 5 5    =     7 7 7
3 3 3           6 6 6           9 9 9



Muhammad
