[R] replace() in matrix

[Tord Snall]

Dear all,
How do I replace values of a matrix, for exemple I want the matrix

1	24	1	1	1
24	1	1	1	1
1	1	1	45	104
1	1	45	1	92
1	1	104	92	1

to be replaced by 

0	24	0	0	0
24	0	0	0	0
0	0	0	45	104
0	0	45	0	92
0	0	104	92	0

Could someone please help me with that?

Thanks in advance!

Sincerely,
Tord Snäll
