Hi All,
I am trying to replace the "NA" values in a matrix by using the following
function:
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".
rep=function(name){
m=as.matrix(name)
for(i in 1:length(m)){
for(j in 1:length(m)){
if(is.na(m[i,j])){
m[i,j]=0
}}}}
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?
Thanks
