Hi everyone,
I am trying to use the values from every cell of the data frame in a
further calculation.
This is the code that I am using to catch every element of the data-frame.
while (a<=10)
{
while (b<=10)
{
n<-as.numeric(df[a,b)];
...;
}
}
The problem is that when I print out 'n' I get the following errors :
"NULL" (if printed without as.numeric), and "numeric(0)" if printed with
the as.numeric.
Again, if I use the same command without the loop, it gives the correct
answer.
Would be grateful for your inputs and ideas on this matter. Thanks in
advance,
Sahana.
