Hi All,

I am trying to replace the "NA" values in a matrix by using the following
it gets a "name" of the matrix or list or vector and turns it to a matrix
called "m". 
then checks the elements of the matrix and if any of them is "NA" replace
them with "0".

for(i in 1:length(m)){
 for(j in 1:length(m)){

when I use the function with the following matrix:

      X1  X2  X3    X5
X1  1.00 NA NA -0.25
X2    NA  1 NA    NA
X3    NA NA  1    NA
X5 -0.25 NA NA  1.00

I get this error: "subscript out of bounds".
I used debug on "rep" function and it seems it works for i=1 and j=1&2&3&4&5
after that, when it's suppose to go to i=2 I get the error.
any idea why and how to fix it?
